U can do what is the strongest paper towel
Answer: 90 kgm/s
Explanation:
The momentum (linear momentum) 
is given by the following equation:
Where:
is the mass of the skater
is the velocity
In this situation the skater has two values of momentum:
Initial momentum: 
Final momentum: 
Where:
So, if we want to calculate the difference in the magnitude of the skater's momentum, we have to write the following equation(assuming the mass of the skater remains constant):
Finally:
Answer:
Kinetic Energy
Explanation:
The potential energy is being converted into kinetic energy. The hitter has struck the ball transferring the kinetic energy from the swinging bat to the ball.
Sup Milk,
Sublimation = Energy is absorbed and a solid turns to a gas.
Condensation = Energy is released and a gas changes to a liquid.
Evaporation = Energy is absorbed into a liquid to turn it into a gas.
I actually know the answer to this one, you use pennies to find the atomic weight of a penny, it really doesn't have a weight. LOL
