Mys 1 7 pt Match the correct dimension to the corresponding physical quantity A L/T B L/T2s heet of E T me, first Duration of a trip DE. 2 AO BO CO DO EO p Speed of light heet and 3 AO BO cO DO EO b Displacement between two points Life of a star 5 AO BO CO DO EO p Velocity of a rocket 6 AO BO cO DO EO D Height of a mountain 7 AO BO DO EO D Mass of the Moon 8 AC I. If an object has a constant (non zero) speed and a fixed ection of motion, what can we say about it? 0-21677 9.AO The acceleration is constantly increasing. BO The acceleration is zero. CO The position in space is constant. DO The net force is increasing EO The displacement vector is constant.Explanation / Answer
A] L/T represents length / time hence the speed/velocity
B] L/T2 has units of acceleration
Similarly, M,L and T has units of mass, length and time respectively.
so, Duration of a trip will have units of time [E]
Speed of light will be L/T [A]
Displacement between two points will be in length dimensions [D]
Life of star will be in time scales [E]
Velocity of a rocket will have units L/T [A]
Height of a mountain is in length units [D]
Mass of the moon is [C].
