Answer:
ELASTIC collision
kinetic energy is conservate
Explanation:
As the ball bounces to the same height, it can be stated that the impact with the floor is ELASTIC.
As the floor does not move the conservation of the moment
po = pf
-mv1 = m v2
- v1 = v2
So the speed with which it descends is equal to the speed with which it rises
Therefore the kinetic energy of the ball before and after the collision is the same
red hot is hot, but other colours are even hotter. stars may be hotter than red hot.
there is also something calle the red shift.
Answer: If all forces acting on a car are zero, than the cars speed is zero since there are no forces to push or pull the car :)

Answer:
folk dancing is old music and ball room is young dancing
Answer:
42.5W
Explanation:
To solve this problem we must go back to the calculations of a weighted average based on the time elapsed thus,
We need to calculate the average power dissipated by the 800\Omega resistor.
Our values are given by:
Aplying the values to the equation we have:
