Answer:
Three Equations of Motion are v = u + at; s = ut + (1/2) at² and v² = u² + 2as and these can be derived with the help of velocity time graphs using definition acceleration.

Answer:
Time, t = 2 seconds
Explanation:
Given the following data;
Mass, m = 50 kg
Initial velocity, u = 0 m/s (since it's starting from rest).
Final velocity, v = 8 m/s
Force, F = 200 N
To find the time, we would use the following formula;
Making time, t the subject of formula, we have;
Substituting into the formula, we have;
Time, t = 2 seconds
Answer:
D
Explanation:
Copper wire at higher temperature
The distance between the plates is 7.1 * 10^-7 m
<h3>What is the distance?</h3>
The capacitor is a device that is used to store charges. The capacitor always has a dielectric that is placed between the capacitors that separates them.
Given that;
C = εoA/d
C = capacitance
εo = permittivity of free space
A = cross sectional area
d = distance apart
Cd = εoA
d = εoA/C
d = 8.8 * 10^-12 * 8.89 * 10^-4/1.11 * 10^-8
d = 7.1 * 10^-7 m

Answer:
The generator will work only if the magnetic field associated with the turns of coil change.
here both magnet and coil are stationary with respect to each other so no electromagnetic induction would take place. so no indiced current will be produced.
the student has to introduce some mechanism either to rotate the coil or the magnet
