Please help me understand this problem An observer in an inertial reference frame S sees lightning strike simultaneously at two points that are 870 nm apart. He measures that the location of the first lightning strike is given by the four coordinates x1 0 m, y1 0 m, z1 0 m, and t0 s. He measures that the location of the second lightning strike is given by the four coordinates X2 = 870 m, y2 = 0 m, z2 0...
A long wire that is at rest in the Earth reference frame initially carries no current. Observer E in this reference frame measures linear charge densities of ?En = 45.00 ?C/m for the (negative) electrons in the wire and ?Ep = 60.00 ?C/m for the positive ions. A current is created as electrons are made to move through the wire at speed v, M moves along with the electrons at their speed v. What value must v have in order...
A reference frame S' moves with a constant speed v=0.800c along the x axis relative to a second reference frame S. A particle is observed from reference frame S' to be moving with velocity 0.400c (along the positive x' axis). What would be the velocity of the particle as measured by an observer in reference frame S?
At t=1.3s, a firecracker explodes at x=12m in reference frame S. Four seconds later, a second firecracker explodes at x=18m. Reference frame S′ moves in the x-direction at a speed of 4.7 m/s . At time t=0 the origins of frames S and S′ coincide. A) What are the positions of these two events in frame S′? B)What are the times at which these two events occur in frame S′?
Imagine a stationary rod of length l in reference frame ( with ends at 2A = 0 and xb = l. Show that the length contraction l' = (v1 – u2/c2 can be derived by calculating the time At' an observer in O' measures for the rod to pass her origin and then multiplying by its speed, u.
The average lifetime of a pimeson in its own frame of reference (l.e., the proper lifetime) is 2.6 x 10s. (a) If the meson moves with a speed of 0.99c, what is its mean lifetime as measured by an observer on Earth? (b) What is the average distance it travels before decaying, as measured by an observer on Earth? (c) What distance would it travel if time dilation did not occur? m Need Help? Read Master it

2. A horizontal spring is oscillating and has mass of 200 g. If the spring constant of it is 80 N/m, (a) find out its time period, (b) if spring constant changed to 20 N/m, what will be its time period? (c) If length of the spring is tripled, what will be its time period?
