Answer:
Explanation:
Given
Initial velocity u = 200m/s
Final velocity = 4m/s
Distance S = 4000m
Required
Acceleration
Substitute the given parameters into the formula
v² = u²+2as
4² = 200²+2a(4000)
16 = 40000+8000a
8000a = 16-40000
8000a = -39,984
a = - 39,984/8000
a = -4.998m/s²
Hence the acceleration is -4.998m/s²

Answer:
Explanation:
The electrostatic potential energy is given by the following formula
Now, we will apply this formula to both cases:
So, the change in the potential energy is
D.to bring light together
It would be the temperature of the steel decreases and the temperature of the water increases
