#SPJ11

Answer:

The answer is 1200

Explanation:

Answer:

height = 45 m

Explanation:

Initial velocity = 0 m/s

Final velocity = 30 m/s

Acceleration due to gravity = +10m/s^2 ( because ball is going down )

Using the eqn of motion

\( {v}^{2} - {u}^{2} = 2gh\)

where v= final velocity ; u = initial velocity ; g = acceleration due to gravity ; h = height

So,

\( {30}^{2} - {0}^{2} = 2 \times 10 \times h\)

\( = > 20h = 900\)

\( = > h = \frac{900}{20} = 45\)

All the paper clips, coiled wire with nail and wrapping or coiling the wire more times are the correct answers.

All the paper clips will the wire wrapped around the nail just a few times pick up. A coiled wire with nail in the center is the electromagnet design which is most successful in picking up the most paper clips. Wrapping or coiling the wire more times around the nail make the electromagnet more stronger.

If an iron nail that was much thicker was used, it will make the magnet stronger that leads to strong electromagnetism. There are three main parts that is necessary for making a motor i.e. a rotor, a stator and a commutator.

These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current. Motors comprise of loops of wire in a magnetic field.

When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates the shaft that leads to the generation of electricity. Water pump, mixer and washing machine are three appliances in your house that use a motor that turns electrical energy into mechanical energy.

Answer:

\(\sqrt{3}\frac{kq^{2}}{a^{2} }\)

Explanation:

none sadly

The net electric force on the charge is located at the lower right-hand corner of the triangle is \(Fr = \sqrt{3} \times\dfrac{q^2}{4 \times \pi \times 0 \times a^2 }\).

Electric force is the attraction or repulsive interaction between any two charged things. Similar to any force, Newton's laws of motion describe how it affects the target body and how it does so. One of the many forces that affect objects is the electric force.

The given electrostatic force is:

F = k  x Q1 x Q2 / R²

here, Q1 & Q2 = charges

R = distance between charges

The force between q and q

F1 = k x q x q / a² = F

The force between q and '-2q'

F2 = k x q x 2 x q / a²  = 2 x F (towards '-2q' charge)

From the diagram given below, angle between F1 & F2 = A = 120°

So, the resultant force will be:

\(Fr = \sqrt(F1^2 + F2^2 + 2 \times F1 \times F2 \times cosA)\\Fr = \sqrt(F^2 + (2 \times F)^2 + 2 \timesF \times2 \timesF \timescos(120)\\Fr = \sqrt(5 \times F^2 - 2 \timesF^2)\\Fr = F \times \sqrt(3)\)

Therefore, the net electric force on the charge is located at the lower right-hand corner of the triangle is \(Fr = \sqrt{3} \times\dfrac{q^2}{4 \times \pi \times 0 \times a^2 }\).

(b) The direction of the current will into the page.

(c) The polarity of A will be positive and L will be negative.

(d)  The current flowing through the wire is 0.224 A.

The emf induced in the wire is calculated as follows;

EMF = BLv

EMF = (8 x 10⁻²) x 0.2 x 7

EMF = 0.112 V

Since, the magnetic field is out of the page, the current will follow counter clockwise and will point into the page.

The current is flowing counter currently, hence the polarity of A will be positive and L will be negative.

If the pressure reading on a vacuum gauge rises from 100 microns to 5,000 microns when the vacuum pump is turned off and stays there, this may indicate that there is a leak in the vacuum system.

When the vacuum pump is turned on, it creates a low-pressure environment by removing gas molecules from the system, causing the pressure reading on the gauge to decrease. When the pump is turned off, the pressure in the system starts to equilibrate with the ambient pressure, causing the pressure reading on the gauge to increase.

If the pressure reading on the gauge continues to rise and stabilize at a higher value than the initial pressure after the pump is turned off, it suggests that there is a leak in the vacuum system that is allowing air or other gases to enter. The leak could be at any point in the vacuum system, such as a damaged O-ring, a loose fitting, or a crack in the system.

The average force on the puck by the stick is 448 N

To find the average force on the hockey puck, we can use the impulse-momentum theorem:

Impulse = Change in momentum

The impulse on the puck can be calculated as:

Impulse = mass x change in velocity
Impulse = 0.16 kg x (9 m/s - (-5 m/s))
Impulse = 0.16 kg x 14 m/s
Impulse = 2.24 N*s

The change in velocity is negative because the puck is moving in the opposite direction after the impact.

The impulse on the puck is equal to the average force multiplied by the time of contact:

Impulse = average force x time
2.24 N*s = average force x 0.005 s
average force = 2.24 N*s / 0.005 s
average force = 448 N

Therefore, the average force is 448 N.

Option D) 1.5 m/s² is the correct answer.

The magnitude of the acceleration of the car is 1.5 m/s².

given the data in the question;

record of the observation;

Time(s)      Speed(m/s)

3.0                4.0

5.0                7.0

6.0                8.5

Since its undergoing constant acceleration, we can make use any two from the three data recorded.

So, lets consider motion between t₁ = 3.0s and t₂ = 5.0s

Initial velocity at t₁ ; u = 4.0 m/s

final velocity at t₂; v = 7.0 m/s

Now, Time Elapsed; \(t = t_2 - t_1 = 7.0s - 5.0s = 2.0s\)

To determine the magnitude of acceleration "a", we use the first equation of motion which says;

\(v = u + at\)

we make "a" the subject of the formula

\(a =\frac{v - u}{t}\)

so we substitute in our values;

\(a = \frac{(7.0m/s) - (4.0m/s)}{2.0s}\)

\(a = \frac{3.0m/s}{2.0s}\)

\(a = 1.5 m/s^2\)

If you measure the average brightness and pulsation period of a cepheid variable star, you can also determine its distance.

Cepheid variable stars belong to a class of stars that have a distinct relationship between variation period and luminosity.

Their period of cycle and luminosity are closely related to each other and they differ in temperature and diameter.

As their brightness increases and decreases, therefore, it helps out in the measurement of intergalactic and interstellar distances.

The changes in amplitude of their motion and cycle period have a definite impact on their brightness which enables us to determine their distance.

The arrow is propelled forward by muscular force. The arrow ultimately hits the ground due to the weight of gravity and air resistance.

This explains the reason the arrow was shot: Gravity's downward pull and air resistance have an effect on the arrow, causing it to eventually sink to the ground.

The arrow first moves forward in a straight line, but as gravity pulls it downward, it eventually collapses and comes to rest.

When comparing the motions of a baseball thrown from a height of 10 ft and a ball that is simply dropped from the same height, there are distinct differences.

The thrown baseball exhibits a combination of vertical and horizontal motion. It follows a curved path due to the initial throwing velocity and the force of gravity, resulting in a parabolic trajectory. In contrast, the dropped ball experiences only vertical motion, falling straight down toward the ground in a vertical line. While both objects are affected by gravity, the thrown baseball's additional horizontal velocity allows it to cover a longer distance and follow a more complex path compared to the vertically descending dropped the ball.

Therefore, the thrown baseball exhibits both vertical and horizontal motion, following a curved trajectory due to the combination of the initial throwing velocity and the force of gravity. The dropped ball, on the other hand, experiences only vertical motion, falling straight down toward the ground along a vertical line.
