Ashish Singh 6 years, 5 months ago

Relative velocity is defined as the rate of change relative position of one object with respect to another.

0Thank You

Yogita Ingle 6 years, 5 months ago

Relative Velocity

This is the velocity of an object relative to some other object which might be stationary, moving slowly, moving with same velocity, moving with higher velocity or moving in opposite direction.

If initial position of two objects A and B are x_A (0) and x_B (0), the position at time t will be,

x_A (t) = x_A (0) + v_A t
x_B (t) = x_B (0) + v_B t
Displacement from object A to B, [ x_B (0) - x_A (0) ] + (v_B -v_A)t
Velocity of B relative to A = v_BA = v_B – v_A
Velocity of A relative to B = v_AB = v_A – v_B

Why is 82°32'E taken as the standard meridian of India

Posted by Bikash Guha Neogi 6 years, 5 months ago

CBSE > Class 11 > Geography

1 answers

Yogita Ingle 6 years, 5 months ago

From Gujarat to Arunachal Pradesh there is a time lag of two hours. Hence, time along the Standard Meridian of India (82° 30' E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country. Otherwise different regions of India would have different times which would create problems; so, to have one common standard times for the whole country has been selected and called Indian Standard Time (IST).
