one more question when working problems like this and others with realtive velocity c will always be the speed of light value ? if so then how can something such as V=0.50c be able to be sub in for v^2/c^2
Homework Statement
The Millenia is catching up to the Galaxa at a rate of 0.55c when the captian of the Millenia decides its time to fire a missle. He uses a laser range finder to determine the distance to Galaxa and then he fires a missle that is moving at a speed of 0.45c.

Homework Statement
An unstable particle called the pion has a mean lifetime of 25ns in its own rest frame. A beam of of pions travels through the lab with a speed of 0.60c.
a) what is the mean lifetime of the pions as measured in the lab frame?
b) how far does a pion travel ( as measured...
for the second part of the question, if a refracting telescope functions like a compound microscope does that mean that you would use the same angular equation?
M= -L/foX N/Fe
Homework Statement
a) what is the angular size of the moon as viewed from the Earth's surface?
b) The objective and eyepiece of a refracting telescope have focal lenghts 80cm and 2.0cm. What is the angular size of the moon as viewed though this telescope?
mean radius of the moon-...

oh i think i got it you use n=1.00 sin60= 1.20sin theta 1 and then solve for theta 1 and sub in all down the layers until you use n=1.00 and solve for theta i. the angle is the same going out of the layers as it was going in?
