Answer 1

Answer:

The amount of daily energy each body requires depends on an individuals daily energy consumption and metabolic energy requirements which can be estimated by body weight and activity level. The total energy consumption value is divided by 4.18 kJ in order to convert the value into kilocalories (1 kcal = 4.18 kJ)

Explanation:

Answer 2

Answer: please mark brainliest

Explanation:

TE = PE + KE       (te= total energy)

pe= mgh (potential energy)

ke= 1\2 m v^2 (kinetic energy)

m=mass

g= acceleration due to gravity

h=height

v=velocity

or mc^2

where

E = energy

m = mass

c = the speed of light
