What is a tree doing when it is growing from the energy it receives from the sun?

A: It’s is taking advantage of energy flowing from high to low

B: it is taking advantage of energy flowing from low to high

C: it is in violation of the law of the second law of thermodynamics

A. It is taking advantage of energy flowing from high to low.

Explanation:

Plants and trees use the solar energy for the process of photosynthesis, and then they utilized that energy obtained from photosynthesis for their growth. It does not violates the second law of thermodynamics. which says that the no process can occur that can cause the reduction in the entropy on its own. As it may seem in this case that the disorder solar energy is converting into the orderly structures like leaves and flowers. The reason behind the fact is that the energy obtained from the sun is released in the form of heat during photosynthesis and some of the energy is utilized in the formation of leaves and flowers etc. So the net entropy in this case always inceases and the flow of energy is from high to low.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
