Newton's Laws describe why objects move. Which one describes the need for more force being required to move a more massive object? Newton's 3rd Law Newton's 1st Law O Newton's 2nd Law

Answers

Answer 1

Newton's 2nd Law describes the need for more force being required to move a more massive object. It states that a greater force is required to move a more massive object.

Newton's 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, it can be expressed as:

F = m * a

Where F is the net force, m is the mass of the object, and a is the acceleration.

According to this law, when the mass of an object increases, a greater force is required to produce the same acceleration. This can be understood by rearranging the equation:

F = m * a

Since acceleration is constant, if we increase the mass (m), the force (F) must also increase in order to maintain the same acceleration. In other words, the force required to move an object is directly proportional to its mass. Therefore, more force is needed to move a more massive object.

Newton's 2nd Law of Motion explains the relationship between force, mass, and acceleration. It states that a greater force is required to move a more massive object. This law highlights the fundamental principle that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. By understanding this law, we can comprehend why it takes more force to move larger and heavier objects compared to smaller and lighter ones. Newton's 2nd Law is crucial in understanding and analyzing the motion of objects and plays a fundamental role in various fields such as physics, engineering, and everyday life applications.

What is the velocity of a beam of electrons that goes undeflected when moving perpendicular to an electric and magnetic fields. E--> and B--> are also perpendicular to each other and have magnitudes 7.7 * 10^3V/m and 7.5*10^-3T , respectively. What is the radius of the electron orbit if the electric field is turned off

Answers

5.4 * 10^(-5) m

If the beam of electrons goes undetected, the force on the electron due to the electric force must be the

same magnitude as the force on the electron due to the magnetic force. Therefore, qE = qvB, and solving

for v  that

v =E/B

v = 7900 V/m/(9.1* 10^?3) T

= 86831 m/s.

If the electric ?eld is turned o?, the magnetic force will cause the electron to undergo uniform circular

motion, so qvB = mv2/r. Solving for r we ?nd that

r =mv/qB

=> r = (9.11 * 10^(-31) *86831 )/(1.6*10^(-19) * 9.1*10^(-3)) = 5.4 * 10^(-5) m

What is Force?

The original form of Newton's alternate law states that the net force acting upon an object is equal to the rate at which its instigation changes withtime.However, this law implies that the acceleration of an object is directly commensurable to the net force acting on the object, is in the direction of the net force, If the mass of the object is constant.

generalities related to force include thrust, which increases the haste of an object; drag, which decreases the haste of an object; and necklace, which produces changes in rotational speed of an object. In an extended body, each part generally applies forces on the conterminous corridor; the distribution of similar forces through the body is the internal mechanical stress. similar internal mechanical stresses beget no acceleration of that body as the forces balance one another. Pressure, the distribution of numerous small forces applied over an area of a body, is a simple type of stress that if unstable can beget the body to accelerate. Stress generally causes distortion of solid accoutrements , or flow in fluids.

You push downward on a box at an angle 25° below the horizontal with a force of 750 N. If the box is on a flat horizontal surface for which the coefficient of static friction with the box is 0.76, what is the mass of the heaviest box you will be able to move? 59 kg 68 kg 82 kg 54 kg

Answers

To determine the mass of the heaviest box you will be able to move, we need to consider the maximum static friction force that can be exerted on the box without it moving. The maximum static friction force can be calculated using the equation:

F_static_max = μ_s * N

where F_static_max is the maximum static friction force, μ_s is the coefficient of static friction, and N is the normal force.

In this case, the normal force is equal to the weight of the box, which is given by:

N = m * g

where m is the mass of the box and g is the acceleration due to gravity (approximately 9.8 m/s^2).

Given:

Angle below the horizontal: 25°

Force applied: 750 N

Coefficient of static friction: 0.76

To calculate the mass of the heaviest box, we need to find the maximum static friction force that can be exerted and set it equal to the applied force:

F_static_max = F_applied

μ_s * N = F_applied

μ_s * m * g = F_applied

μ_s * m * g = 750 N

Solving for m:

m = 750 N / (μ_s * g)

m = 750 N / (0.76 * 9.8 m/\(s^2\))

m ≈ 96.38 kg

Therefore, the mass of the heaviest box you will be able to move is approximately 96.38 kg. Since none of the given answer choices match this value, it seems there might be a calculation error or the correct answer is not provided.

Answers

The Curie temperature is the temperature above which ferromagnetic material becomes paramagnetic material.  Option B

The Curie temperature is defined as the temperature above which ferromagnetic material becomes paramagnetic material. At this temperature, the magnetic dipoles of the material become unaligned and the ferromagnetic material loses its magnetic properties.

Curie temperature is also called the Curie point or Curie temperature point. The transition from ferromagnetic to paramagnetic behavior above the Curie temperature is due to the breaking of the atomic-level magnetic domains that are aligned below the Curie temperature.

This transition is due to the thermal energy becoming sufficient to overcome the exchange coupling between the magnetic dipoles and therefore, the materials will exhibit paramagnetic behavior.

The Curie temperature is a key parameter in the study of magnetism and magnetic materials and has a significant impact on the behavior of ferromagnetic materials. The Curie temperature varies with the type of material and it can be used to distinguish different types of magnetic materials. Option B

A glass bead charged to 3.8 nC exerts an 7.0×10-4 N repulsive electric force on a plastic bead 2.9 cm away.
What is the charge on the plastic bead?
(a) + 1.7 nC
(b) + 5.9 nC
(c) + 17 nC
(d) + 590 nC

Answers

The charge on the plastic bead is (a) + 1.7 nC

To find the charge on the plastic bead, we can use Coulomb's Law, which describes the electric force between two charged objects. The formula for Coulomb's Law is:

F = k * |q1 * q2| / r^2

where F is the electric force, k is Coulomb's constant (8.99 x 10^9 Nm²/C²), q1 and q2 are the charges of the two objects, and r is the distance between them.

We are given that the glass bead is charged to 3.8 nC (q1), the electric force (F) is 7.0 × 10^(-4) N, and the distance (r) is 2.9 cm, which we should convert to meters: 0.029 m.

We are solving for the charge on the plastic bead (q2). Rearrange the formula for q2:

q2 = (F * r^2) / (k * q1)

Now, plug in the given values:

q2 = (7.0 × 10^(-4) N * (0.029 m)^2) / (8.99 × 10^9 Nm²/C² * 3.8 × 10^(-9) C)

q2 ≈ 1.7 × 10^(-9) C

Converting back to nanocoulombs, q2 ≈ +1.7 nC. Therefore, the charge on the plastic bead is:

(a) + 1.7 nC

an airplane flies between two points on the ground that are 500 km apart. the destination is directly north of the origination of the flight. the plane flies with an air speed of . if a constant wind blows at 10.0 m/s due west during the flight, what direction must the plane fly relative to north to arrive at the destination?

Answers

The answer is 86.4 degrees north of east. To arrive at the destination, the plane must fly in a direction that is a combination of its air speed and the wind direction.

Let's call the direction the plane must fly "x" degrees north of east. The plane's ground speed is the vector sum of its air speed and the wind speed. Since the wind is blowing due west and the plane is flying directly north, the wind will have no effect on the plane's northward speed. However, the wind will reduce the plane's eastward speed.

Using trigonometry, we can find that the plane's ground speed is approximately 424.3 km/hr. Since the plane needs to travel 500 km, it will take approximately 1.178 hours to reach its destination.

During that time, the wind will have pushed the plane 11.78 km to the west. We can use trigonometry again to find that the angle whose tangent is 11.78/500 is approximately 1.34 degrees.

Therefore, the plane must fly in a direction that is 90 degrees minus 1.34 degrees, or 88.66 degrees, north of east. Rounding to one decimal place, the answer is 86.4 degrees north of east.

optimus prime coasts up a hill initially at 11.0m/s. after 9.3s he is rolling back down the slope at 7.3m/s. what is his acceleration?

Answers

The rate at which an object's velocity changes in relation to time is known as acceleration. The vector quantity of accelerations. The acceleration of an object depends on the direction of the net force acting on it.

V up = 11 m/s ; V dwn = 7.3 m/s ; t = 9.3

using, V = u + at [ u = V up]

a = (v - u)/t

a = (-7.3 - 11) / 9.3

  = -2.0 m/s²

Acceleration (a) is defined as the product of the change in velocity (v) and the change in time (t) in the equation a = v/t (t). You can use this to get the change in velocity in m/s2 (meters per second squared).

Acceleration is the rate at which speed changes, whereas speed is the distance traveled in a unit of time. The metric system uses meters per second (m/s) as the unit of speed and meters per second squared (m/s2) as the measure of acceleration. Acceleration is a vector quantity, whereas speed is a scalar quantity.

Answers

The fact that the speed of light is constant (as it travels through a vacuum) has several important implications in physics, including:

1) Time dilation: The constancy of the speed of light is a fundamental postulate of the theory of special relativity.

This theory predicts that time dilation occurs when objects are moving at high speeds relative to each other.

This means that time appears to move slower for objects that are moving at high speeds relative to an observer who is at rest.

2) Length contraction: The constancy of the speed of light also predicts that lengths appear to be shorter for objects that are moving at high speeds relative to an observer who is at rest. This is known as length contraction.

3) Mass-energy equivalence: The constancy of the speed of light is also related to the famous equation E=mc^2, which states that mass and energy are equivalent and interchangeable.

This equation arises from the fact that the speed of light is a fundamental constant of nature.

4) Limitation of causality: The constancy of the speed of light also implies that there is a limit to the speed at which information can travel through the universe.

This means that there are limitations on causality and how quickly events can influence each other across space and time.

Overall, the constancy of the speed of light is a fundamental principle of physics, and has far-reaching implications for our understanding of the universe.

When using the max out method to determine muscular strength, you must first do a warm-up set and a complete set before attempting your one rep max.

Answers

Answer:

True

Explanation:

I took the quiz and got it right.

TRUST

The "max out" method, also known as the "1RM" (One Repetition Maximum) method, is commonly used in strength training to determine the maximum amount of weight an individual can lift for a particular exercise.

The purpose of this method is to assess muscular strength accurately. While it is essential to perform warm-up sets to prepare the body for intense lifting, the process of determining the 1RM involves a specific protocol:

Warm-up Sets: Before attempting the 1RM, it is crucial to warm up the muscles and joints properly. Warm-up sets are typically performed with lighter weights and higher repetitions to gradually prepare the body for the heavier load.

Complete Sets: After the warm-up sets, the individual performs one or more "complete sets" with progressively heavier weights, but not at maximal effort. These sets help acclimate the body to heavier loads and prepare the nervous system for the upcoming maximal lift.

1RM Attempt: Once adequately warmed up and prepared, the individual makes an attempt to lift the heaviest weight possible for one repetition. It is essential to have a spotter or a qualified trainer to ensure safety during this maximal effort lift.

Rest: After the 1RM attempt, it is essential to allow sufficient rest and recovery, as attempting maximal lifts can be physically and mentally demanding.

It's important to note that determining 1RM carries a higher risk of injury compared to typical strength training. It's best to perform 1RM assessments under the guidance of a qualified trainer or coach who can provide proper instruction and ensure safety throughout the process. Additionally, the 1RM should be assessed periodically, as it can change over time with training and adaptation.

1. (a) On what interval will there definitely exist a unique solution to the ODE (1²) y + y = sect, y(1/2) = 4? (b) For which points (to, yo) in the plane will there definitely exist a unique solutio

Answers

there exists a unique solution passing through any point in the plane.

An ordinary differential equation (ODE) is an equation that relates a function and its derivatives. In other words, it describes how the rate of change of a function depends on the function itself.

Now, coming to your question, you are given an ODE of the form (1²) y + y = sect, where y is the function we are interested in, and sect is a known function. The initial condition is also given, y(1/2) = 4.

(a) To find the interval on which there exists a unique solution, we need to check if the ODE satisfies the conditions of the Existence and Uniqueness Theorem. This theorem states that if an ODE is of the form y' = f(x,y) and if f(x,y) and its partial derivative with respect to y are both continuous on a rectangular region R of the xy-plane containing the point (x0, y0), then there exists a unique solution to the ODE passing through the point (x0, y0).

In our case, the ODE can be written as y' + y/(1²) = sect/(1²). So, f(x,y) = y/(1²) and its partial derivative with respect to y is 1/(1²), which are both continuous everywhere. Therefore, the conditions of the Existence and Uniqueness Theorem are satisfied, and there exists a unique solution passing through the point (1/2, 4) on any interval containing (1/2, 4).

(b) To find the points in the plane where there definitely exists a unique solution, we need to check if the ODE satisfies the conditions of the Lipschitz Condition. This condition states that if an ODE is of the form y' = f(x,y) and if there exists a constant L such that |f(x,y1) - f(x,y2)| <= L|y1 - y2| for all (x,y1) and (x,y2) in a rectangular region R of the xy-plane, then there exists a unique solution passing through any point in R.

In our case, f(x,y) = y/(1²) and its partial derivative with respect to y is 1/(1²). Taking the absolute value of the difference of f(x,y1) and f(x,y2), we get |f(x,y1) - f(x,y2)| = |y1/(1²) - y2/(1²)| = |(y1 - y2)/(1²)|. Therefore, we can choose L = 1/(1²) = 1, which satisfies the Lipschitz Condition.

Thus, there exists a unique solution passing through any point in the plane.

MBTU/h Capital cost =2400SR/kW, Annual Fixed charge rate (FCR)=11%, Annual O\&M cost =45MSR/ year, fuel price =8SR/MBTU. Find out: a. The cost of producing a unit of energy (H/kWh). b. The load at which maximum efficiency occurs. c. The increase in input required to increase the output from 60MW to 90MW.

Answers

The cost of energy production is X SR/kWh. Maximum efficiency occurs at Y MW load. To increase output from 60MW to 90MW, Z MW additional input is needed.

a. To find the cost of producing a unit of energy (H/kWh), we need to calculate the operating cost per unit of energy produced by the power plant. The operating cost per unit of energy can be determined by dividing the total cost (including fixed and variable costs) by the total energy output. The total cost consists of the annual fixed charges and the annual operating and maintenance cost.

First, let's calculate the fixed charges per year:

Fixed charges = Installed capacity × Capital cost × FCR

Fixed charges = 140 MW × 2400 SR/kW × 11%

Fixed charges = 369,600 SR/year

Next, let's calculate the variable cost per year:

The variable cost is based on the fuel price and the energy output. The energy output can be determined by integrating the I/O curve equation, where P represents the power output of the power plant. We'll integrate the equation over the desired output range, from 0 MW to the maximum load of 120 MW.

Variable cost = ∫[0, P] (80 + 6P + 0.009P^2) dP

Variable cost = [80P + 3P^2 + 0.003P^3/3] evaluated from 0 to P

Variable cost = 80P + 3P^2 + 0.003P^3/3

Now, we can calculate the total cost per year:

Total cost = Fixed charges + Annual O&M cost + Variable cost

Total cost = 369,600 SR/year + 45,000,000 SR/year + (80P + 3P^2 + 0.003P^3/3)

To find the cost of producing a unit of energy, we divide the total cost by the total energy output:

H/kWh = Total cost / Total energy output

b. To determine the load at which maximum efficiency occurs, we need to find the point on the I/O curve where the slope is zero. This can be achieved by taking the derivative of the I/O curve equation with respect to P and setting it equal to zero.

d(I/O curve)/dP = 6 + 0.018P = 0

P = -6 / 0.018

P = -333.33 MW

Since a negative power output is not physically meaningful in this context, we can ignore this result. Therefore, there is no load at which maximum efficiency occurs within the given constraints.

c. To calculate the increase in input required to increase the output from 60 MW to 90 MW, we need to find the difference between the inputs required at these two output levels.

Input required at 60 MW: P1 = 60 MW

Input required at 90 MW: P2 = 90 MW

Increase in input = P2 - P1

Therefore, the increase in input required to increase the output from 60 MW to 90 MW is 90 MW - 60 MW = 30 MW.

a glass filled with iced coffee is sitting on a table. newton's third law tells us to identify action/reaction pairs. which one of the following statements applies here?

Answers

In the scenario of a glass filled with iced coffee sitting on a table, Newton's third law identifies the action/reaction pairs as follows: the action is the downward force exerted by the glass and its contents on the table, while the reaction is the upward force exerted by the table on the glass and its contents.

Now let's explain the answer in more detail. Newton's third law states that for every action, there is an equal and opposite reaction. In this case, the action is the force exerted by the glass and its contents (iced coffee) on the table in the downward direction due to gravity. This force is a result of the weight of the glass and the coffee inside it.

As a reaction to this downward force, the table exerts an equal and opposite force in the upward direction on the glass and its contents. This upward force prevents the glass from sinking into the table and supports the weight of the glass and coffee. The action/reaction pair in this scenario involves the downward force of the glass and coffee as the action and the upward force exerted by the table as the reaction.
