Question

What is the approximate linear speed (in km/hr) of a point at
the equator and pole due to motion of earth about its own
axis if the radius of the earth is 6400 km?​

Answer 1

Explanation:

Time period of rotation of earth,T = 24h

Radius Of the earth, R = 64,00 km

As v = R and 2π/T,

v= 2πR/T = [2×3.14×6400/24] km/h

Answer. = 1675km/h.
