thank u for the tips yet still I get the wrong number when I plug my numbers in: -->With what speed will a clock have to be moving in order to run at rate that is one-half the rate of a clock at rest? For the problem, I plug in T=(1/2)t and t-zero=t, because I think the moving clock the...

In the time lorenz formulas, how can u tell what the difference between t-zero and T is? t-zero T= -------------------- ------------------- | 1 - (v^2/c^2) \| for example in the following...

Question: Use Newton's version of Kepler's third law to find the mass of Earth. The moon is 3.9*10^(8) m away from Earth, and the moon has a period of 27.33 days. I just have trouble with using the correct units...thanks for any help!

What about it? I believe that the speed of light and laser vary by a tiny amount (and I believe that is significant in studying Physics). Is that right? I need expert confirmation on this.

Hi, Are the speeds of all different colors of light exactly the same? And has this been done experimentally? Have they actually let colors into a system where it calculated its speed. (I know that Albert Michelson measured the speed of pure light_I just don't know if he or anyone else has done...

1. A student stands on a bathroom scale in an elevator at rest on the 64th floor of a building. The scale reads 836 N. As the elevator moves up, the scale reading increases to 936 N, then decreases back to 836 N. Find the acceleration of the elevator. 2. The instruments attached to a weather...

I have recently borrowed a new book from the local library: Calculus of Linear and Nonlinear Functions by Francis J. Flanigan and Jerry L. Kazdan. I have already finished first-year Calculus and I was wondering if this type of book would prepare me well for second-year Calculus in...

Hi, I have been looking through the main NASA site for an opportunity of working at NASA in the future. I have found the career that I found interesting: professional engineering. I have been informed that NASA is the best place to work and have always dreamed of going there myself to see...

Wow, you really caught my mistake! I understand now, instead of dividing by (v2) I should have brought -12v(v2) to the other side and factored to find (v2). Thanks a bunch.

The theory of Big Bang tells us all matter was at rest until a trigger set off and then matter was converted into huge amounts of energy and as a result caused a huge explosion which created the universe.

HI, I am wondering how to solve this physics question: -We have an object A and we have an object B -We place these objects at a distance from each other. -Object A has mass m. -Object B has mass 3m. -Object A moves toward object B with velocity v. -Object B moves toward object...

Thanks, now I know. Can you also tell me how it was done mathematically?

Is the following equation which relates to light refraction index and the amount which bounces back been proven experimental or theoretically(mathematicaly)? R = [(n1-n2)/(n1+n2)]
