Answer:
The answer is radio waves
Answer:
The ball land at 3.00 m.
Explanation:
Given that,
Speed = 40 m/s
Angle = 35°
Height h = 1 m
Height of fence h'= 12 m
We need to calculate the horizontal velocity
Using formula of horizontal velocity
We need to calculate the time
Using formula of time
We need to calculate the vertical velocity
We need to calculate the vertical position
Using formula of distance
Put the value into the formula
We need to calculate the distance
Hence, The ball land at 3.00 m.
I believe anticline (caused by compressional stress)
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
