What is rise in temperature of a collective drop when initially 1 gm and 2 gm drops travel with velocities 10 cm/sec and 15 cm/sec.
Consider a constellation of 3 stars, A, B and C forming a right triangle with angle ABC = 90o and angle BAC = 30o. If the distance between star A and B is 3√3 x 1013 km, then how much time does light take to travel from star C to B with a speed of 3 x 108 m/s?
