The time needed is
Explanation:
From the question we are told that
The magnitude of the stimulated acceleration due gravity is
The diameter of the spaceship is
Generally the force acting on the spaceship is
Given that the spaceship is rotating it implies that the force experienced by the occupant is a centripetal force so
Thus
=>
Generally the speed of this spaceship is mathematically represented as
=>
=>
=>
=>
substituting values
Answer:

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 />
<u>Note that</u>:
The gravitational potential energy =
where m: is the mass, g: the acceleration due to the gravity and h is the height from the earth surface
Then, we can increase the gravitational potential energy by increasing the mass or the height from the earth surface
<u>In our question</u>, we can increase the gravitational potential energy by
<u>A) Strap a boulder to the car so that it wights more.</u>
