B!
This is because gravitational pull energy needs a height. The higher the height the higher the energy.
Final velocity = 30 m/s
acceleration = 30/20 = 1.5 m/^2
Answer:
The distance is
Explanation:
From the question we are told that
The distance of separation is
The wavelength is
The distance of the screen is
Generally the distance of a fringe from the central maxima is mathematically represented as
For the first dark fringe m = 0
For the second dark fringe m = 1
So the distance from the first dark fringe on one side of the central maximum to the second dark fringe on the other side is
In your question where the ask is to calculate the charge that the small sphere carries which is the mass of it is 441g moving at an acceleration of 13m/s^2 nad having and electric field of 5N/C. So the formula in getting the charge is mutliply the mass and the quotients of Acceleration and the Electric Field so the answer is 1,146.6
