Physics - August 2006

If the universe is expanding, then surely the bonds in the molecules that make up my body are also expanding? Could this eventually change their behaviour, making life impossible?

(I can't even spell physics..) OK let's say you have a cup of hot water and a cup of cold water. you poor them both at the same time into a room temp container. does the cold water try to cool the hot water or the hot water try to warm up the cold water??? Also why when you put ice cubes in room temp water the ice makes the drink cool...why doesn't the drink make the ice warm? maybe it is because the difference....if we were to put ice into boiling water..the hot drink would warm the ice....

(Sorry, I can't spell!)

I was just wondering. Also, if you are a physicist - would you mind sharing YOUR views on the different dimentions.

Thanks ;-)

Acc to Newton, Gravitational force is the force acting between two centers of bodies like the centre of the earth and the moon. We also know gravitons are responsible for Gravity. If we equate the two it means gravitons orginate from the centre of any body. Where is the assumption worng?

(c) the speed of light in a vacuum is defined as ~186,000 miles per second. Has anyone try to question why? Why isn't it perhaps 100,000,000 miles per second( or some other number)? Nature just chose that speed? Does the Maxwell equation imply this or is it derived from this? Has anyone worked to think *outside of the box* and have a thoery of maybe an undiscovered force effecting it or something impeding it? Thank you if anyone knows!

Two masses, m1 = 28.0 kg and m2 = 42.0 kg, are connected by a rope that hangs over a pulley. The pulley is a uniform cylinder of radius 0.50 m and mass 5 kg. Initially m1 is on the ground and m2 rests 2.5 m above the ground. If the system is released, use conservation of energy to determine the speed of m2 just before it strikes the ground. Assume the pulley bearing is frictionless.

At some clear and starry nites, I often point out the stars with my laser pointer. I wondered, how far does the ray travel? Does it ever reach the distance stars out there?
