Hey I was given 3 problems for homework, I just need help on some and the others I want to make sure i did it right.(adsbygoogle = window.adsbygoogle || []).push({});

Problem 1: What is gamma for an object with speed B = 0.1?

Problem 2: You are at rest, and see me as moving with a speed of

B = 0.05. I see a car moving with a speed of B = 0.05. How fast do

you measure the car to be moving? In particular, how much

different is the car's speed from B = 0.1?

Problem 3: Assume that you can measure the phase difference to 1 degree.

What is the minimum w(omega) that you can measure? Assume light with

a wave length of 1000 nm, and a 0.1 m2 coil with 1000 loops.

for 1 I know gamma=1/sq. root(1-B^2). Now is that all you do, because it just seems to easy.

for 2 I 'm not sure how to start it

for 3 I know difference in phase= 8(pi)(Area)(3 of loops)(omega) /c(wavelength) , but how do i find the area?
