Answer:

Explanation:
From the question we are told that:
Separation Distance 
Potential difference 
Generally the equation for Electric Field strength is mathematically given by



Let at any instant of time the speed is vo and the angle made by the bike with the horizontal is given
now we have
component of speed in x direction given as

component of speed in y direction will be

now from above two equations we can say that here
= angle with the horizontal at any instant
and since here it is a sine curve so we know that

so we have slope of graph

Answer:

Explanation:
Given that,
Force, F = 52 N
Mass of the block, m = 4 kg
We need to find the acceleration of the object. We know that,
F = ma
Put the values,

So, the acceleration of the object is equal to
.
Because the ball is a sphere and there's nothing that can actually stop a sphere unless you cover it with something that will actually stop it, for example like your hand.
Answer:
400 m/s
Explanation:
If it is moving at a velocity of 80 m/s from rest, then after 5 s it would be at 400 m/s.
80 x 5 = 400
