Answer 1

Step-by-step explanation:

$\huge\purple{ₐₙₛwₑᵣ}$

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

Answer 2

Answer:

I am thanking

Step-by-step explanation:

Diameter = 70 cm

Radius = 70/2 = 35 cm

1. 5 Km = 150000 cm

Solution:

Circumference = 2πr

\implies⟹ 2 x 22/7 x 35

\implies⟹ = 220 cm

It means, 220 cm = 1 revolution

Then = 150000/ 220

\implies⟹ = 168 revolution (approx)
