If the earth did not have internal energy, which of the following carbon cycle process would not be possible?

a. respiration

b. consumption

c. rock formation

d. burning fossil fuels

If the Earth did not have internal energy, the carbon cycle process which would not be possible is: C. rock formation.

Carbon cycle can be defined as the series of biogeochemical processes through which atoms of carbon or carbon compounds are interconverted and used within an environment, by transporting carbon from the atmosphere to the Earth and then back to the atmosphere.

Basically, the four (4) main processes associated with carbon cycle include the following:

Of all the aforementioned processes, only rock formation requires that the Earth has sufficient internal energy for the movement of materials around the core and the mantle, thereby, leading to gradual but significant changes within the Earth's crust.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
