If the average energy per neutrino was approximately 4.2MeV, estimate the amount of energy released via neutrinos during the supernova explosion.
Suppose two clouds containing equal numbers of electrons are separated by a distance of 2.4x1022m. If the magnitude of the electric force between the clouds is 1.0N, what is the charge of each cloud?
What are comets like when they are on the part of their orbit that is far from the Sun? Are they as easy to observe?
When the connection is made, the wires are pushed aside by the repulsive force between the wires, and each wire has an initial horizontal velocity of magnitude v_0. Assume that the time for the capacitor to discharge is negligible compared to the
A charge of -3.35 nC and a charge of -7.00 nC are separated by a distance of 40.0 cm. Find the position at which a third charge of +7.10 nC can be placed so that the net electrostatic force on it is zero.
The electric field intensity at a point 29.8 cm radially outward from its axis (measured from the midpoint of the shell ) is 58300 N/C. What is the electric field at a point 5.39 cm from the axis?
Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.30 s. The astronaut is strapped into a seat 4.20 m from the axis.
