I KNOW that you must have seen this formula before. It gives
the distance covered in a certain time of accelerated motion:
D = 1/2 A T²
Distance covered= (1/2) (Acceleration) (Time squared) .
The question gives us the acceleration and the time.
I've got a weird idea: Let's plug them into the formula. OK ?
Distance = (1/2) (10 m/s²) (10 sec)²
= (5 m/s²) (100 sec²)
= 500 meters .

Answer:
The last option is correct
ΔT1 = 4 sec ΔT2 = 4 sec ΔT3 = 4 sec
S = V0 t + 1/2 a t^2
S1 = 1/2 a t^2 = 8 a where V0 is the speed at the start of the interval
During any interval (of 4 sec) the particle travels 1/2 a t^2 = 8 a due to its acceleration - and you need to include the speed at the start of the interval
S1 = 8a
S2 = 8 a + 8 a = 16 a
S3 = 16 a + 8 a = 24 a
Note: V2 = V1 + a t for any interval
V2 - V1 = V1 + a t - V1 = a t
and a = (V2 - V1) / t = a the speed increase is constant during the interval

The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.
