I would say the answer is 3 because by falling technically the ball would be kind of moving in the air. Plus potential energy is when for example a soccer ball isnt moving
Answer:
The water turns in to vapor and rises in the air leaving the salt behind
Explanation:
Answer:
False
Explanation:
It is actually the exact opposite.
Considering conservation of mechanical energy we have:
K+U (start)= K+U (end)
Where:
K=kinetic energy=
![\frac{1}{2}m v^{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7Dm%20v%5E%7B2%7D%20%20)
U=potential energy=
![mgh](https://tex.z-dn.net/?f=mgh)
So:
0.05*0.95*9.81+0 (start) = 0+K (end)
K (end)=0.5 Joules
