I hope this helped :D
Answer:
a.)It will rise faster in cooler air
a.) heat
Explanation:
i
A hot air balloon rises faster if cold air were to surround it due to density differences between the air in the two medium.
- Hot air is less dense as the average kinetic energy of the molecules is greater.
- Cold air is denser.
- This density contrast causes the balloon to move up at a high pressure.
ii. Heat
The average kinetic energy of the molecules in a substance is termed heat.
Heat is a form of thermal energy measured by the kinetic energy possessed by molecules in a substance.

*2&3 i amn't sure about them*
I am pretty sure that the answer is D. The entire sequence of human DNA was identified.
I don't have any evidence that this is the answers, just that while reading my textbook, it said that the project identified the entire sequence of human DNA, so it was pretty much a word for word answer. I hope this helps!!!
<span>For 0 < x < 90
</span>
cos (90-x) = sin (x),
and
sin (90-x) = cos(x)
Let's just try and pick the top one, the equation will become
<span>cos (90-40) = sin (40)</span>
<span>Cos (50) = sin (40)</span>
