I woke up every hour for 4 hours to check if the shower happened. Now it's morning and I don't know if it happened or not. Did it?

A truck and a car are both moving with a contant velocity of magnitude 'v'. Why is it difficult to change the motion of a truck when compared to the state of the motion in a car.

I'll give 10 points for the best answer.

It's easy. I'll give you a hint: The car has less mass

Do you think we're wasting our money on the space program? I think its just a left over tradition from the cold war. Why do we feel the need to waste money when we could be solving problems down here on earth like our education system? Would it be such a crazy idea if we took those billions of dollars and spent it on making a better society? People tell me the technology from the space program has influenced our lives. That may be true, but who's lives? THE RICH! Those are the users of top end technology. We keep blasting people into space and they float up there and then come down. Oh, and the space shuttle is an old piece of crap. Awesome!

A large truck and a car, both moving with a velocity of magnitude 'v', have a head-on collision and both of them come to a halt after that. If the collision lasts for one second:
1) Which vehicle experiences the greater force of impact?
2) Which vehicle experiences the greater change in momentum?
3) Which vehicle experiences the greater acceleration?
4) Why is the car likely to suffer more damage than the truck?

If you get it right, I'll give you 10 points! (it's so easy!)

A girl jumps from a tree onto the ground. As she falls she speeds up.Explain in details how the law of conservation of momentum applies in this case?

Can I consider the girl and the earth(the ground) as a system?? Why or why not??
PLEASE HELP ME WITH MOMENTUM PROBLEMS. I would be so happy if you can tell me some advices about learning momentum. Thanks in advance!!!

Suppose that you are shopping in the mall around 7:00 p.m. on Christmas Eve. There are tons of last minute shoppers around when the fire alarm sounds. It turns out that there are only 3 doors to exit the ENTIRE mall from!

These three doors are set up in parallel. Or--
The three doors are set up in series.
Post which situation you would choose to exit through. Explain using at least 5 sentences, proper spelling and grammar, why you have chosen this situation and how it relates to Resistors in a circuit. Respond to at least one other classmate about their post.

(a) A sample of liquid water of mass of 10 g and a temperature 20°C is placed into a large thermally insulated vessel containing steam at 100°C.

How much water will be present when equilibrium is achieved?

(b) A glass flask whose volume is 1000.0 cm^3 at 0.0 ºC is completely filled with mercury at this temperature. When the flask and mercury are warmed to 55 ºC, 8.45 cm^3 of mercury overflow.

If the coefficient of volume expansion of mercury is
1.82 × 10^(-4) K^(-1) , compute the coefficient of volume expansion of the glass.
