True, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.
<h3>Relationship between dielectric material and electric field</h3>
The electric field in a capacitor separates the negative and positive charges in the dielectric material, this causes an attractive force between each plate and the dielectric.
The dielectric material can store electric energy due to its polarization in the presence of external electric field, which causes the positive charge to store on one electrode and negative charge on the other.
Thus, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

As per kinematics equation we know that
final speed of the car = 0 m/s
initial speed is given as 30 m/s
distance moved = 100 m
now we have
now braking force is given as
now for mass we know that the weight of car is
so mass of car is
now we have
Part b)
Again we have
final speed of the car = 0 m/s
initial speed is given as 30 m/s
distance moved = 10 m
now we have
now braking force is given as
mass of car is
now we have
