Answer:
Many parts of the cardiovascular system (including the heart) are influenced by gravity. On Earth, for example, the veins in our legs work against gravity to get blood back to the heart. Without gravity, however, the heart and blood vessels change – and the longer the flight, the more severe the changes.
The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:
Where;
- is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;
Change in internal energy (ΔH) = 715 Joules.

Answer:
okay I will do that since you asked do nicely :)
Answer:
The inner core has the highest density
Explanation:
Despite high temperatures should be melting the metals in the inner core, the extreme pressure keeps the earth's inner core in a sold phase. The solid metals make the earth's core very dense, at about 17 g/cm³
No beacuse the other layer may be to cold or hot for humans to survive in
