Answer:
When the ball is held motionless above the floor, the ball possesses only GPE energy.If the ball is dropped, its GPE energy decreases as it falls.If the ball is dropped, its KE energy increases as it falls.
Explanation:
If the ball is held motionless, then its kinetic energy is equal to zero, since kinetic energy depends on the velocity. And the ball is held above the ground, which means it possesses gravitational potential energy.
If the ball is dropped, its height will decrease, therefore its gravitational potential energy will decrease. Along the way, the ball will be in free fall, and therefore its velocity will increase, hence its kinetic energy.
If you look at the picture you will see how, but the answer is 0.5 Hz.
Answer:
Electric force on the charge will be equal to -1742000 N
Explanation:
We have given electric field at a point is E = 260000 N/C
And charge q = -6.7 C
We have to find the force on that charge
Force on the charge is equal to Force = charge × electric field ( multiplication of electric field and charge )
So force will be equal to
So electric force on the charge will be equal to -1742000 N
