For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity <span>and h is the height in meters.Watch that gravitational </span>potential energy<span> has the same units as kinetic </span>energy.
Answer:
node
Explanation:
on the graph node is higher than antinode
so it can get or hear loud sounds faster
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
