A particle is located within the hollow interior of a uniform spherical shell. Which of the following describes the net gravitational force on the particle due to the shell? zero if the particle is at the center of the shell but nonzero at other locations within the hollow zero for any location of the particle within the hollow.
Two radio antennas are separated by 2.00 m. Both broadcast identical 750MHz waves. If you walk around the antennas in a circle of radius 10.00 m, how many maxima will you detect.
An alpha particle with kinetic energy 17 MeV makes a head-on collision with a lead nucleus at rest. What is the distance of closest approach of two particles.
Compute the distance of two point's p1 and p2 in the x-y plane with the following Cartesian coordinates: p1= (-5m, +8m), p2= (+3m, +2m). Draw the position vectors into appropriate-points.
A steel aircraft carrier is 364m long when moving through the icy North Atlantic at a temperature of 2.4°C. By how much does the carrier lengthen as it is traveling in the warm Mediterranean Sea at a temperature of 21° C.
Calculate the coil's self-inductance. If the current decreases uniformly from 5.00 to 2.00 in 3.00, estimate the self-induced emf in the coil.
An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0-kg pilot does not want her radial acceleration to exceed 7g. (a) What is the least radius of the circular path? (b) At this radius, what is the force causing the centripe..
