Answer:
A
Explanation:
because in the moving object there's a certain energy applied
Answer:
<u />
<u />
Explanation:
From the question we are told that:
The Electric field of strength direction =Right
The Velocity of The First Electron=V_0
The Velocity of The Second Electron=V_0
Therefore

Generally, the equation for the Horizontal Displacement of electron is mathematically given by

Where
Acceleration is given as

And
Time

Therefore horizontal displacement towards the left is

<u />
<u />
The change in velocity from 30 m/s north to 40 m/s south is a change of 70 m/s south
Answer:
second one is correct that is right
Answer:
500kg
Explanation:
mass = newtons/force divided by the acceleration rate
m = 30,000/60
m = 500
