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.

Answer:

Explanation:
r = Radius of atom = 
m = Mass of chlorine atom = 
= Angular speed = 
The moment of inertia of the system is given by

Kinetic energy is given by

The rotational kinetic energy of one molecule of the atom is 
The filter would need to absorb every color EXCEPT yellow. It would have to absorb red orange green blue and violet.
For number 52, 1kg=1000 g
So, if she has 750 grams:
1,000g-750g= 250g
She would need 250g more soil
