Answer:
Explanation:
Given that,
The current flowing in the circuit, I = 3 A
The power of the battery, P = 25 W
We need to find the resistance of the battery. We know that the power of the battery is given by the formula as follows :
Put all the values to find R.
So, the resistance is equal to .
The speed of an object at rest is 0 m/s. We can use logic to figure this out. Hope this helps!
Decide which components you wish to assess yourself. There is no set order in which you do this. you could, for an example assess one or two elements and skip the rest.

<u>Answer:</u>
a) Height of cliff = 44.145 meter
b) 7.5 meter far from its base the diver hit the water.
<u>Explanation:</u>
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Diver's vertical motion:
Initial velocity = 0 m/s, acceleration = 9.8 , we need to calculate displacement when time is 3 seconds.
So height of cliff = 44.145 meter.
b) Diver's horizontal motion:
Initial velocity = 2.5 m/s, acceleration = 0 , we need to calculate displacement when time is 3 seconds.
So 7.5 meter far from its base the diver hit the water.
