Question 1

State whether true or false.Piston of the engine in a motor car exhibits Oscillatory motion.

Accepted Answer

A piston of a car engine exhibits an oscillatory motion. It maintains a back and forth motion.

Question 2

The motion described by the needle of sewing machine is oscillatory motion. True or false

Accepted Answer

A needle of sewing machine performs a back and forth motion. This kind is called oscillatory motion.

Question 3

Water waves in a shallow dish are $6.0\ m$ long. At one point, the water moves up and down at a rate of $4.8$ oscillations/s. Speed of the wave is:

Accepted Answer

Question 4

The time period of a simple pendulum is independent of its length.

Accepted Answer

The length of a pendulum is the distance between point of suspension and centre of the bob

Question 5

Define Oscillatory motion.

Accepted Answer

The 'to-and-fro' or 'back or forth' motion described by an object as a whole along the same path without any change in the shape of the object is called Oscillatory motion

Question 6

In SHM the net force towards mean position is related to its displacement (x) from mean position by the relation

Accepted Answer

Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.$F=-kx$$\implies F\propto x$

Question 7

What is a seconds' pendulum?

Accepted Answer

A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing, a frequency of 1/2 Hz.

Question 8

One oscillation completed by a vibrating body in one second is known as

Accepted Answer

Number of oscillations made by a vibrating body of an medium in 1 sec is known as frequency of a wave. And one oscillation completed by a vibrating body in one second is said to be 1 Hz.

Question 9

The motion of a pendulum is an example of :

Accepted Answer

The motion of simple pendulum is an example of oscillatory motion.

Question 10

It takes 0.2 s for a pendulum bob to move from mean position to one end. What is the time period of pendulum?

Accepted Answer

time period will be time between the bob going from one mean position to another and then return back to mean positiontherefore T = 0.8 s
