Q2.Who Received  the first Nobel prize in physics in India? 

a. Dr. C.V. Raman

b. Dr. Hargobind Khurana 

C. Prof. C.N.R Rao.

d. Prof. Narlikar.

Exp- Dr. C V Raman was the first recipient to get noble prize in India for work in the field of light scattering in the year of 1930. C.V Raman is known as Sir Chandrasekhara Venkata Raman as a full name.

Q3. Newton's laws of motion do not hold good for objects?

a. At rest

b. Moving slowly 

c. Moving with high velocity

d. Moving with velocity comparable to velocity of light.

Exp- Newton's law of motion is applicable for all  conditions but it does not work when objects moves more than or comparable to velocity of light so, always keep in your mind we should apply newton's law when velocity of object is low with respect to velocity of light. 

Option d is correct.

Q4. Which is not a unit of energy?

a. Watt second

b. Kilo watt hour

c. Watt

d. Joule.

Exp- The unit of energy can be watt second ,Kilo watt hour and Joule but watt can't be unit of energy. 

Watt is commercial unit of power.

Or we can say in our day to day life we use watt for taking our meter reading in our household.

Q5. Sound travels in the form of

a. Transverse wave

b. Longitudinal wave

c. Stationary waves

d. Both a and B. 

Exp- There are so many of us who got confused in this type of question but always keep  in your mind the following points about sound

1. Sound is both transverse as well as longitudinal waves.

2. The speed of sound is maximum in solid followed by liquid and least in gas.

3. Sound can propagate through a medium of air, water and solids.

4. In gases and water sound travels as a transversed wave while in solid sound travels as a longitudinal wave.

Q6. The second law of motion states that

Exp- According to second law of motion, the rate of change of momentum of an object is proportional to the net force applied on the object in the direction of net force.

Q7.In which medium sound can't be travelled

a. Steel

b. Vacuum. 

c. Air

d. Milk

Exp-Sound can't be travel without air I. E., sound can't travel in vacuum.
