A tap supplies water at 26°C while another supplies water at 82°C. If a man wishes to bath with water at 40°C the ratio of the mass of hot water to that of cold water is A 1:3 B 3:1 C 3:7 D 7:3 E 15:8

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

1/0.14nm = 10^10/1.4 a lot

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
