83) Which of the following statement is correct?

The periodic time of a particle moving with simple harmonic motion is the time taken by a particle for one complete oscillation.

The periodic time of a particle moving with simple harmonic motion is directly proportional to its angular velocity.

The velocity of the particle moving with simple harmonic motion is zero at the mean position.

The acceleration of the particle moving with simple harmonic motion is maximum at the mean position.

Answer is:

The periodic time of a particle moving with simple harmonic motion is the time taken by a particle for one complete oscillation.

86) The slope on the road surface generally provided on the curves is known as

Answer is:

angle of banking

Explanation:

Whenever a roadway (or railway) is laid on a curved path, then its outer edge is always made higher than the inner edge, to keep the vehicle in equilibrium while in motion.

The amount by which the outer edge is raised, is known as cant or superelevation. In case of roadways, the process of providing superelevation is known as banking of the road.

The general practice, to define the superelevation in roadways, is to mention the angle of inclination (also called angle of banking) of the road surface.
In case of railways, the general practice to define the superelevation, is to mention the difference of levels between the two rails.
