What is your thoughts on this supject? I disagree with the big bang theory, and I have many reasons why it is incorrect. One of which is the fact that I believe in the living breathing God, the one who son died for you and me. I believe that God created all things and there is no other explanation for it other than God.

What is your thinking on this subject?

I watched the tape of the space shuttle Atlantis take off. When the shuttle reached orbit the shuttle was separated from the external fuel tank. The tank began to fall to earth, yet the shuttle stayed in orbit. This is my question, why did the external fuel tank fall and the shuttle did not?

I think i have the answers, but i am not sure about the method. Can you check these and tell me why i am right?

1) A force accelerates a body of mass M. The same force applied to a second body produces three times the acceleration. What is the mass of the second body?
My friend tells me the answer is M/3 and i don't understand why.

2) A mass m is hanging on a string that passes over a pulley and is then attached to another mass 3m that is resting on a horizontal table. Neglect friction. Mass m is held motionless and is then released. When it has fallen a distance h, it will have a speed v. Find the formula for v.
On this one, i get the squareroot(gh/2), but as i am following my work, parts of it don't make sense to me. Can you show me if this is correct or not?

This is it for now, thanks so much!!!!!

Can anyone help me solve this question? Thanks a lot for your help!

How can an object in uniform circular motion be moving at a constant speed and at the same time be constantly accelerating? For this same object, can we apply the following equations of motion:

v(final) = v(initial) + at
d(final) = d(initial) + v(initial) t + 1/2 at2 ?

An object rests on an inclined surface. If the surface is made steeper, what does the normal force on the object do?

Increase
Decrease (i think this is right, but just checking)
Stay the same
Normal Force is zero (pretty sure its not this)
cannot be determined (pretty sure its not this)

if this is not true is one or the other non-zero. i am pretty sure that they are both zero but I just figured I'd check because im a lazy right now.

I have a physics question that I can't figure out. Thanks to everyone who can answer!!!

A record was set for stair climbing when a man ran up the 1600 steps of the Empire State Building in 10 minutes and 59 seconds. If the height gain of each step was .20 m, and the man's mass was 70 kg, what was his average power output during the climb? Give your answer in both watts and horsepower.

Thanks to everybody who can help me!!!

or more?
If you have a bottle of water in the car, and it is very hot outside, like 30 degrees Celsius. Inside the car temperature is more than that, and so is the water temperature in a bottle.When you drink the water feels hot, so while driving (at safe speed, that is max 120 km/h), you keep the botle outside the car, in order to lower it's temperature.
Me and my husband argued about water's temperature. He said that the temp will fall under environment's temperature and I said it won't because the "outside" counts as a big termostat. We finally put a bet an decided to ask around.
