WebSep 7, 2024 · PROBLEM -2. The moon is observed from two diametrically opposite points A and B on Earth. The angle θ subtended at the moon by the two directions of observation is 1 o 54′ . Given the diameter of the Earth to be about 1.276 × 10 7 m, compute the distance of the moon from the Earth. WebSolution:- velocity is [L]/ [t] and the units in the SI system for velocity are therefore m s-1: v = L/t where v is the velocity. Now V = AL where V is the volume of a length of pipe L of cross-sectional area A i.e. L = V/A. Therefore v = V/At Checking this dimensionally [L] [t]-1 = [L]3[L]-2[t]-1 = [L] [t]-1 which is correct.
