The two strings are taut. When the system is released from rest, it accelerates at 2 m/s2 then, Mass of A = 8m/5 kg.

Let the mass of the body A be ‘m’.

The two strings are taut so they exert a tension ‘T’ on body A.

Let ‘a’ be the acceleration produced in the system.

The free body diagram of body A is given below: mA + 2T = mA + ma = mA + m(2)mA + 10T = mA + ma = mA + m(2)

As the two strings are taut, we can say that tension in both strings is equal.

Therefore 2T = 10T or T = 5T As the body A is resting on a smooth horizontal table, there is no friction force acting on the body A.

The net force acting on body A is the force due to tension in the strings. ma = 2T – mg …(1)

As per the given problem, the system is released from rest.

Hence the initial velocity is zero.

Also, we are given that the system accelerates at 2 m/s2.

Therefore a = 2 m/s2 …(2)

From the equations (1) and (2), we get, m(2) = 2T – mg …(3)⇒ m(2) = 2×5m – mg⇒ 2m = 10m – g⇒ g = 8m/5

Thus, the mass of A is 8m/5 kg.

Answer: Mass of A = 8m/5 kg.

= 25 mph

Answer:

Explanation:

We know that:

Work:

Hence, the speed is 25 m/h.

Answer:

50 N

Explanation:

To determine the force exerted on the particle, we can use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). Mathematically, this can be expressed as:

F = m * a

Given that the mass of the particle is 5 kg and the acceleration is 10 m/s^2, we can substitute these values into the formula:

F = 5 kg * 10 m/s^2

F = 50 N

Answer:

In a material, the magnetic behavior depends on the alignment of magnetic moments of the atoms. Magnetic moments are generated by the motion of the electrons in the atoms. When the magnetic moments of atoms in a material are aligned in a specific pattern, it creates a magnetic field which results in the material being magnetic.

In many materials, the magnetic behavior arises due to the alignment of magnetic domains, which are regions of atoms with magnetic moments aligned in the same direction. When many domains with aligned magnetic moments are present in a material, the material becomes magnetic.

The magnetic behavior of a material depends on the number of electrons and the arrangement of those electrons in the atoms. In particular, for an atom to have a magnetic moment, it must have unpaired electrons, meaning electrons that are not paired with another electron with the opposite spin. When these unpaired electrons in the atoms are aligned, they generate a magnetic moment. If all electrons are paired, there will not be a net magnetic moment, so the material will not be magnetic.

So, in summary, the magnetic behavior of a material is determined by the alignment of magnetic moments of atoms. When the magnetic moments of many atoms in a material align in the same direction, it creates a magnetic field, leading to a material being magnetic. This alignment is usually present in magnetic domains consisting of atoms with unpaired electrons.

Answer:

P.E = 98 Joules

Explanation:

Given the following data;

Mass = 5kg

Speed = 4m/s

Height = 2m

We know that acceleration due to gravity is equal to 9.8m/s²

To find the potential energy;

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

\( P.E = mgh\)

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the equation, we have;

\( P.E = 5*9.8*2\)

P.E = 98 Joules

Initially we choose the ball and earth together as our system. Since there are no external forces acting on them they are said to be in isolated state.

Given that the ball is at rest initially. So u = 0m/s

Finally the ball is moving with velocity = v m/s

The ball is moving downward after falling and earth is moving upwards.

Piy(earth) = -Piy(ball)

The initial momentum is zero as there are at rest and the final momentum  after collision must be zero as they are isolated.

After colliding the ball will stick together with the earth and stops so that the final velocity becomes zero. According to the impulse-momentum theorem, an item will experience an impulse that is equal to the change in its momentum. We can now see how the impulse-momentum theorem demonstrates how a modest net force applied over a prolonged period of time can result in the same velocity change.

Due to the relationship between linear and angular speed, the candidate's speed is 13.3 m/s

A satellite orbiting the earth is one of the example of a circular motion. The satellite will experience gravitational attraction towards the center of the earth. This attraction force provides the centripetal force

Given that a prospective astronaut is spun around in a human centrifuge such that the candidate experiences a centripetal acceleration that is 2.5 times the acceleration due to gravity on the surface of the earth. If the candidate is 7.27 m from the center, the parameters to work on are

To determine the candidate's speed in meters per second, let us first find its angular speed w in rad/s by using the formula

a = w²r

24.5 = 7.27w²

w² = 24.5 / 7.27

w² = 3.37

w = √3.37

w = 1.84 rad/s

The relationship between linear and angular speed is

Explanation:

For this exercise we must use the principle of conservation of energy

starting point. The proton very far from the nucleus

          Em₀ = K = ½ m v²

final point. The point where the proton is stopped (v = 0)

          Em_f = U = q V

where the potential is

          V = k Ze / r²

Let us consider that all the charge of the nucleus is in the center, therefore r is the distance from this point to the proton that is approaching

Energy is conserved

          Em₀ = Em_f

           ½ m v² = e (\(k \frac{Ze}{r^2}\))

          \(r^2 = \frac{ 2 k \ Ze^2}{ 2m}\)

with this expression we can find the closest approach distance (r)

Therefore, the ball hits the water 30.1 meters from the bottom of the cliff.

A vector is a mathematical object that has both magnitude (size) and direction. It can be used to represent physical quantities that have both a numerical value and a direction, such as velocity, force, or acceleration. A vector can be represented graphically as an arrow, with its length representing its magnitude and its direction indicating its direction. The tail of the arrow represents the starting point of the vector, while the head represents the endpoint. In addition to their graphical representation, vectors can also be described algebraically using components.

Here,

To find the distance from the bottom of the cliff where the ball hits the water, we need to find the time it takes for the ball to hit the water and then use this time to find the vertical displacement of the ball at that time.

First, we can find the time it takes for the ball to hit the water by setting the y-coordinate of its position vector equal to zero (since the water is at ground level):

-4.9t² + 40 = 0

Solving for t, we get:

t = √(40/4.9) = 2.03 seconds

So the ball hits the water after 2.03 seconds.

Next, we can use this time to find the vertical displacement of the ball at that time by plugging in t = 2.03 seconds into the y-component of its position vector:

r_y = -4.9(2.03)² + 40 = 30.1 meters

The Inertial is the resistance of a body at rest to be in motion

Given the following  item

1. 4kg shot put ball  

2. 2,000 kg boulder

The body of greater mass has greater inertia, hence would be harder to accelerate.

An object with a small inertial mass will accelerate more than an object with a large inertial mass when acted upon by the same force.

Of the 2 items in the list, the 2,000 kg boulder has the largest mass, hence it also has the greater inertial  and more difficult to accelerate.

The bottom-most spring going to be after three masses are hung on it is 14.3 cm

(a) is correct option

Explanation:

Given that,

Three identical mass = 6.4 kg

Force constant = 7.8 kN/m

Distance before attached mass = 12 cm

We know that,

When we attached three identical masses then the total mass on the spring will be 3 mg.

We need to find the extension

Using balance equation

\(F=mg\)

\(k\Delta x=mg\)

\(\Delta x=\dfrac{mg}{k}\)

For three masses,

\(\Delta x=\dfrac{3mg}{k}\)

Put the value into the formula

\(\Delta x=\dfrac{3\times6.4\times9.8}{7.8\times10^{3}}\)

\(\Delta x=0.023\ m\)

We need to calculate the length of the bottom spring

Using given length

\(x=\Delta x+0.12\)

Put the value into the formula

\(x=0.023+0.12\)

\(x=0.143\ m\)

\(x=14.3\ cm\)

A ray diagram with given information gives an image location of 10.7 cm on the ruler. This method helps determine characteristics of images formed by lenses.

To build a beam graph to decide the picture area, we first need to draw an outline with the given data. We start by defining an upward boundary to address the focal point, with the ruler and the dark spot on one or the other side of it. We then, at that point, draw a bolt on the left half of the focal point at the 3.0 cm mark.

Then, we draw three beams from the bolt. The primary beam is attracted lined up with the important pivot and goes through the point of convergence on the right half of the focal point.

The subsequent beam goes through the focal point of the focal point and go on in an orderly fashion. The third beam goes through the point of convergence on the left half of the focal point and becomes lined up with the essential pivot subsequent to going from the perspective.

Where these three beams cross on the right half of the focal point is the picture area. For this situation, the beams converge at a point situated at 10.7 cm on the ruler, which is the response to the inquiry. Thusly, the picture is situated at 10.7 cm on the ruler.

This strategy for developing a beam graph is a valuable apparatus in deciding the area and qualities of pictures shaped by focal points, and is a significant idea in the investigation of optics.

Explanation:

Let \(a\) denote the acceleration of this shark.

Let \(v_0\) denote the initial velocity of this shark.

Assume that the acceleration \(a\) of this shark is constant (as it is in this question.) Over a period of time \(t\), the shark would have travelled a distance of:

\(\displaystyle x = \frac{1}{2}\, a\, t^2 + v_0\, t\).

This question is asking for \(v_0\), the initial velocity of this shark at the beginning of this \(0.8\)-second period. Substitute the three known values into the equation:

\(\displaystyle 11.52 = \frac{1}{2}\times 16\times (0.8)^2 + 0.8\, v_0\).

Solve for \(v_0\):

\(v_0 = \displaystyle \frac{11.52 - (1/2) \times 16 \times (0.8)^2}{0.8} = 8.0\; \rm m \cdot s^{-1}\).
