A simple mercury barometer indicates a reading of 760 mmHg when used on Earth to measure an atmospheric pressure of 1.0x10^5 Pa. The pressure of air in a space orbit about the Earth is 0.9x10^5 Pa.
Explain why the barometer cannot be used to measure this pressure and state what would happen if an attempt were made to do so.

A motorboat maintained a constant speed of 15 miles per hour relative to the water in going 10 miles upstream and then returning. The total time for the trip was 1.5 hours. Use this information to find the speed of the current.

Is this the correct way to put it:

10/x+15 + 10/x-15 = 1.5

We had to build mousetrap cars and we have to explain the comparison between the calculated amount of work done to set the trap and the kinetic energy of the car. Is it that if our cars were 100% efficient the kinetic energy would be equal to the amount of work done?

I am in physics 3 this semester and luckily I have made it this far. I am worried that I won't do well on the exams. I already do all the assigned homework.
Thanks
