## Question number: 44

» Oscillations and Waves » Periodic Functions

Assertion-Reason▾

### Assertion (Ꭺ)

In S. H. M. , the motion is ‘to and fro’ and periodic.

### Reason (Ꭱ)

Velocity of the particle (where x is the displacement and k is amplitude)

### Choices

Choice (4) Response

a.

Both Ꭺ and Ꭱ are true and Ꭱ is the correct explanation of Ꭺ

b.

Ꭺ is false but Ꭱ is true

c.

Ꭺ is true but Ꭱ is false

d.

Both Ꭺ and Ꭱ are true but Ꭱ is NOT the correct explanation of Ꭺ

## Question number: 45

» Oscillations and Waves » Simple Pendulum

MCQ▾

### Question

If a simple pendulum oscillates with amplitude of 30 mm and time period of 5 sec, then its maximum velocity is

### Choices

Choice (4) Response

a.

b.

c.

d.

## Question number: 46

» Oscillations and Waves » Periodic Motion - Period Frequency

Assertion-Reason▾

### Assertion (Ꭺ)

The periodic time of a hard spring is less compared to that of a soft spring.

### Reason (Ꭱ)

The periodic time depends upon the spring - constant, and spring constant is large for hard spring.

### Choices

Choice (4) Response

a.

Ꭺ is false but Ꭱ is true

b.

Both Ꭺ and Ꭱ are true and Ꭱ is the correct explanation of Ꭺ

c.

Both Ꭺ and Ꭱ are true but Ꭱ is NOT the correct explanation of Ꭺ
