22. B. When we place a coin in our line of sight, most of the light from the moon will be blocked. It's same like eclipse that we are blocking moon's light. Now measure the distance between your eye and coin. Take ratio as distance between eye and coin to diameter of coin. Now equate this ration of distance between moon and eye to diameter of moon to get the distance.
23. A. Most basic is physics because all the basic principles comes from physics. The concepts we use in chemistry and biology are somewhat derived from physics.
24. D
25. B
26. Velocity - 12 m/s , time - 40 sec
Distance = velocity × time = 12 m/s × 40 sec = 480 m.
