Answer:
False because it has no mass.
Explanation:
The mutual inductance of the two coils is 1.28*10^-3H.
To find the answer, we have to know about the mutual inductance.
<h3>How to find the
mutual inductance of the two coil?</h3>
- We have the expression for emf in terms of mutual inductance and rate of change of current as,
- From the question, it is clear that,
- Thus, the mutual inductance is,
Thus, we can conclude that, the mutual inductance of the two coils is 1.28*10^-3H.

The height of the ball after the given time of motion is 3.275 m.
The given parameters;
- initial velocity of the ball, u = 4 m/s
- height of fall of the ball, h = 2.5 m
- time of motion, t = 0.5 s
The distance traveled by the ball is calculated as follows;
Thus, the height of the ball after the given time of motion is 3.275 m.

Answer:
A correlation coefficient represents the following:
1- The direction of the relationship
2- The strength of the relationship
Answer:
Height, H = 25.04 meters
Explanation:
Initially the ball is at rest, u = 0
Time taken to fall to the ground, t = 2.261 s
Let H is the height from which the ball is released. It can be calculated using the second equation of motion as :
Here, a = g
H = 25.04 meters
So, the ball is released form a height of 25.04 meters. Hence, this is the required solution.
