(i)They are used to find the unit of a given physical quantity in a given system of units.

(ii)They are used to find dimensions of physical constants or coefficients.

(iii)They are used to convert a physical quantity from one system of units to another.

No (2a)

Time of flight: Time of flight (T) is the time required for a projectile to return to the Same level from which it was projected

T= 2usin θ / g

(2b)

Maximum height: Maximum height(H) is the highest vertical distance attained as measured from the horizontal projectile plane.

H = U²sin²θ / 2g

(2c)

Range : Range(R) is defined as the horizontal distance from the point of projection to the point where the projectile hits the projection plane again

R= U²sin2θ / g

No (5a)

Forbidden gap is the group of energy levels that cannot be occupied by the electrons, these energies lies in between conduction band and valence band.

(5b)

(i) free electrons which have negative charges
(ii) holes, which have positive charges

No (7a)

Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

(7b)

(i)by heating past the Curie point

(ii)by applying a strong magnetic field
