Answer with Explanation:
We are given that
Constant speed of Jane=12.6 m/s
a.When Fred can throw the ball 30 m/s
We have to find the angle relative to the horizontal when he throw the ball in order for Sue to see the ball travel vertically upward.
Let 
be the angle .
Therefore,
b.We have to find the height to which ball reach.
This is A.) lake. A river is a small amount of water that isn't always fresh water. A stream is too small. And an ocean is made of salt water.
68% So 68/100 of freshwater is found in ice
Answer:
-9.8 m/s²
0 m/s
Explanation:
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (-9.8 m/s − 9.8 m/s) / 2.0 s
a = -9.8 m/s²
Average velocity is the change in position over change in time.
v = Δx / Δt
v = (0 m − 0 m) / 2.0 s
v = 0 m/s
A deuteron is related to deuterium, which is hydrogen with one neutron in the nucleus.
The charge on the deuteron is 1.6x10^-19C.In half a rev, the charge gets a force of Eq on it.
