Two balls simultaneously ejected (event A) from the point x=0 in some inertial frame. One rolls in the +x direction with speed 0.80 and eventually hits a wall at x = 8.0 ns (event B). The other rolls in the -x direction with speed 0.40, eventually hitting a wall at x = -8.0 ns (event C).
Is the space time interval between B and C space like or time like? Could these events be casually connected?
in a simplified roller bearing, the inner cylinder has a radius of 1.0 cm and is stationary. What is the angular speed of the small cylinders
Two trains, each having a speed of 28 km/h, are headed at each other on the similar straight track. A bird that can fly 56 km/h flies off the front of one train, when they are 66 km apart and heads directly for the other train. On reaching the other ..
A researcher would like to perform an experiment in a zero magnetic field, which means that the field of the earth must be cancelled. Suppose the experiment is done inside a solenoid of diameter 1.2 , length 3.0 , with a total of 9000 turns of wir..

a) calculate E1' and E2', the lorentz transformations of E1 and E2 b) calculate the distances E1E2 and E1'E2' with the four dimensional scalar product of the time position vector within itself
Light from a He-Ne laser (= 632.8) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.10 from the slits. The figure shows the interference pattern observed on the screen.
A sanding disk with rotational inertia 5.4 x 10-3 kg·m2 is linked to an electric drill whose motor delivers a torque of magnitude 10 N·m about the central axis of the disk. About that axis and with torque applied for 72 ms, what is the magnitude o..

A hollow, conducting sphere with an outer radius of 0.253m and an inner radius of 0.190m has a uniform surface charge density of +6.64×10?6 C/m^2. What is the electric flux through a spherical surface just inside the inner surface of the sphere
Given a Nanowire with cross sectional dimensions of 10 nm x 10 nm, what momentum would an electron in the ground state need in order to possess the same energy as a stationary electron (zero momentum) in the n=1,2 state?
Pictured is a thin non-conducting disk of radius R = 7.32 centimeter containing an overall charge Q = -50.0 mC, Compute the potential V at point P placed a distance d = 6.65 centimeter from the disk
