Energy available for sustaining Eric's muscular and nervous activity can be calculated by,
Energy available= Standard molar entropy×Number of moles×Temperature
We have, standard molar entropy of glucose = 182 J/K mol
Number of moles of glucose = 1.80 mol
Body temperature = 36.9° C = 36.9 + 273.15 = 310.05 K
Substituting the value we get,
Energy available = 182×1.80×310.05 = 100,456.2 J
A has less energy and lower frequency, while B has greater energy and higher frequency.
The net force and the net acceleration are zero
Explanation:
In this problem, we have an object falling down. During its fall, it is acted upon two forces:
- The force of gravity, downward
- The air drag, upward
Here we are given that:
The force of gravity is
The air drag is
Therefore, the net force is
According to Newton's second law, we have that the net force on an object is equal to the product between its mass (m) and its acceleration (a):
But in this case,
It follows that
So, the net acceleration is zero.

They are all good, thx for the points btw
