Explanation:

5)both r true band reason is the correct explanation of assertion.

6)both are incorrect

7)a.Mustbbe zero

8)a.Zero

9)c.I and IV

10)d.Displacement

11)The path of an object in uniform motion is a straight line. Uniform Motion: ... In simple words, a body is said to have uniform acceleration if the rate of change of its velocity remains constant.

12)Speed is defined as the distance traveled by a body per unit time. Its SI unit Is m/s

some other units of Speed are= cm/s, cm/min, km/s, km/h, km/min.

13)Speed is defined as the distance traveled by a body per unit time. Its SI unit Is m/s and it's an scalar quantity. while velocity is the rate of change of displacement in a given unit of time and it's a vector quantity it's SI unit is also m/s.

14)(1)Uniform Motion-A body is said to be in uniform motion if it covers equal distance in equal interval of time. (2)Non-uniform Motion-A body is said to be in non-uniform motion if it covers unequal distance in equal intervals of time.

Sorry your section D is not clear.
