Both ends are held up by the watertight pockets which are much less dense than the water around it.
The direction of the friction force F exerted by the horizontal surface on the crate will be in the left direction.
<h3>How to depict the force?</h3>
From the information given, the 85-lb force P is applied to the 200-lb crate, which is stationary before the force is applied.
mg = 200 × 0.2248 × 9.8 = 440.608
The static friction force will be:
= 0.5 × 440.608
= 220.304N
Therefore, the static friction is greater than the force applied. Therefore, there'll be a static friction acting on the box on the left direction.

Answer:
No
Explanation:
Let's assume the gas pressure is constant. Then we can use Charle's law, which states that the volume of the gas is proportional to the absolute temperature (in Kelvin):
This can be rewritten as
where we have
is the initial temperature of the gas
is the final temperature of the gas
Re-arranging the previous equation, we find
so, the volume of the gas decreases by a factor 0.87.
Hmmm, id say cardio.. but i don't know forsure
I believe these are the answers
#1- D
#3-B
#4- D
#5- D
#6-A
#7-B
I was able to get everything except #3
I hope this helps though :)
