The faster car behind is catching up/closing the gap/gaining on
the slow truck in front at the rate of (90 - 50) = 40 km/hr.
At that rate, it takes (100 m) / (40,000 m/hr) = 1/400 of an hour
to reach the truck.
(1/400 hour) x (3,600 seconds/hour) = 3600/400 = <em>9 seconds</em>, exactly
Answer:Uniform between the plates
Explanation:
Electric Field due to infinite sheet with uniform charge is given by

Where
=charge density
=Space Permittivity
From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .
Answer:
Explanation:
From the question,
The kinetic energy of protons
K = 7eV.
Mass of proton and the speed of light are the given parameters.
Please kindly go through the files I attached for a step by step explanation of the answer required.
I think you can just sub the values in? unless the qn is asking for smth else?
law of conservation of energy
aka the first law of thermodynamics
