It does not hurt when an empty hangs lightly against a wall because the wall applies an
equal and opposite reaction force on you. In this case, Newton's third law is applicable.
Our hand hurts, when we are carrying a heavy load. This is because; the downward force acts or
our hand. This downward force depends on the weight of load. In this case, Newton's second law
is applicable.
Pls mark me brainliest answer
Because the average of one measurement would yield to itself, which provides nothing new to us. We need at least two for average to be purposeful.

Answer:
(a) 1.257 x 10^5 J
(b) 1.456 Watt
Explanation:
Volume of blood, v = 7500 L = 7.5 m^3
Height, h = 1.63 m
density of blood, d = 1.05 x 10^3 kg/m^3
(a) work done = m x g x h
W = v x d x g x h = 7.5 x 1.05 x 1000 x 9.8 x 1.63 = 1.257 x 10^5 J
(b) time = 1 day = 24 x 60 x 60 s = 86400 seconds
Power = Work / time = 1.257 x 10^5 / 86400 = 1.456 Watt
