Question 10 of 14

11. Assertion- To specify the speed of an object we required its magnitude.

Reason-magnitude is the scalar quantity.

Question 11 of 14

12. Assertion- To specify the speed of an object we required its magnitude.
Reason- Speed is a vector quantity.

Question 12 of 14

13. Assertion- The velocity of an object can be a uniform as well as variable.
Reason- Velocity can be changed by changing the object speed and direction of motion.

Question 13 of 14

14. Assertion- Earth is an example of uniform circular motion.
Reason- When an object moves in a circular path with the uniform speed the speed of motion is known as uniform circular motion.
