To solve this, you’d multiply 55 by 4, because he is travelling 55 miles every hour, for four hours, which means 55 miles every hour. The answer would be 220.
Answer:
The displacement of the air drop after 3 second is 18.27 m.
Explanation:
Mass of the rain drop = m = 
Weight of the rain drop = W
Duration of time = t = 3 seconds
Drag force on rain drop = 
Motion of the rain drop:
Net force on the rain drop , F= W - D
v = 12.18 m/s
Initial velocity of the rain drop = u = 0 (since, it is starting from rest)
v=u+at (First equation of motion)
(second equation of motion)
s = 18.27 m
The displacement of the air drop after 3 second is 18.27 m.

Answer: 9) when water is put inside a pot and put on a stove, the fire heats the pot, heat is transferred through the pot by conduction, the next step here in heat transfer by convection which happens in the water in the pot, when heat is transferred from the pot to the water the water molecules gain kinetic energy and moves up while the heavier molecules of the water comes down to get heated, this continues until heat is transferred throughout the water by convection, radiation occur when the quantity of the water is getting reduced.
10) same principle applies to that of the stove, but the difference is that the heat comes from sun and not from fire, the ice-cream is heated by conduction and heat is spread throughout the ice cream by convection , and radiation comes from the sun to the ice cream
