I personally would live on Mars cuz that is red cuz
The electric force (and the gravitational force too) is inversely proportional
to the square of the distance between the objects involved.
In this question, the distance is increased by a factor of (1.25/0.95) .
So the electric force will change by the factor of (0.95/1.25)² .
The new force is
(1.32 N) · (0.95/1.25)² = 0.762... newton (rounded)
Answer:
im pretty sure it B but I recommend waiting for another person. I used the workdone formula (Force*Dictance*cos(theta) and got 55 Joules
Explanation:
Answer:
5.886 J
Explanation:
Given:
The mass of the book is, kg
Height of lift is, m
Acceleration due to gravity is, m/s²
Now, gain in gravitational potential energy is a function of change in position and is given as:
Here, is the change in gravitational potential energy.
Plug in 0.5 kg for , 9.81 for and 1.2 for . Solve for
Therefore, the gain in gravitational energy of the book is 5.886 J.
