Answer:
Explanation:
Let the mass of bullet is m, initial velocity of bullet is vi and c be the specific heat of the bullet.
Kinetic energy, K = 1/2 mvi^2
According to the question, 50% of the kinetic energy is equal to the heat energy absorbed by the bullet.
50% of K = mass of bullet x specific heat x rise in temperature
1/4 mvi^2 = m x c x ΔT
Answer: By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life.
Explanation: Plzz mark me as brainliest !!
Answer:
when you bring two objects of different temperatures together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Answer:
so gravity will be same as that of surface of earth
Explanation:
As we know that the acceleration due to gravity is given as
here we have
we know that for earth we have
now if the radius and mass is given as above
so gravity will be same as that of surface of earth
Answer:
frictonal force due to the surface of irregularities
