I am bit rusty on my physics. I hope some of you can help me and check if what I have done is correct. I have an appliance which is rated for a voltage range of 110-127 volts, drawing 4.5 amps. I would like to use it on 220 volts using a 500 Watts converter. However, I just wanted to make sure...

What about gaining or losing KE due to collisions? I don't have an answer to the OP's question, but my 2 cents suggestion is that his question deals with the microscopic behavior of the gas and he is wondering about the macroscopic effect of temperature as a result. Isn't the net energy change...

I hold the marble so that the light on the photogate turns red (indicating an obstruction), then gradually raise it till it is green (ubobstructed). I realize that this is a very crude method, but I try several times to find the point where the marble is just clearing off from the path of the...

Homework Statement Can free fall acceleration be determined by dropping a marble through a single photogate? The CPO timer attached to the photogate can measure the time it takes for the marble to pass between the arms. Knowing the diameter of the marble enables one to calculate the speed. If...
