Answer: unequal forces
Explanation: in order for something to accelerate it must speed up or slow down . When unequal forces react it casuse a change in motion which is also know as acceleration .
Answer:
30643 J
Explanation:
= Vacuum permeability = 
t = Time taken = 1 ns
c = Speed of light = 
= Maximum electric field strength = 
A = Area = 
Magnitude of magnetic field is given by
Intensity is given by
Power, intensity and time have the relation
The energy it delivers is 30643 J
Answer:
<h2>470.59 kg</h2>
Explanation:
The the mass of the car can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>470.59 kg</h3>
Hope this helps you
Kepler derived his three laws of planetary motion entirely from
observations of the planets and their motions in the sky.
Newton published his law of universal gravitation almost a hundred
years later. Using some calculus and some analytic geometry, which
any serious sophomore in an engineering college should be able to do,
it can be shown that IF Newton's law of gravitation is correct, then it MUST
lead to Kepler's laws. Gravity, as Newton described it, must make the planets
in their orbits behave exactly as they do.
This demonstration is a tremendous boost for the work of both Kepler
and Newton.
