A neutron decays into a proton and an electron. Write the decay reactions of a neutron using both nucleons and quarks. You will need to show two reactions.
An LR circuit contains an ideal 60-V battery, a 51-H inductor having no resistance, a 21- resistor, and a switch S, all in series. what is the current in the circuit
A net force of 1.6 x 10-15 Newton acts on an electron over a displacement of 5.0 centimeter, in the same direction as the net force. Find the change in kinetic energy of the electron
In a photoelectric experiment it is found that a stopping potential of 1.00 V is needed to stop all the electrons, determine Planck's constant and the work function of the metal
A 300 ball on a 70--long string is swung in a vertical circle about a point 200 above the floor. What was the tension in the string an instant before it broke
A point charge of 8.40 mC is surrounded by an equipotential surface with a radius of 0.284 meter. Determine what the electric potential on the surface

An m=8.25 Kg mass is suspended on a string that is pulled upward by the force of F=83.3 N. If the upward velocity of the mass is 3.25 m/s right now, what is the velocity 5.50 s later.
A rod (length = 80 cm) with a rectangular cross section (1.5 mm ? 2.0 mm) has a resistance of 0.20 ?. What is the resistivity of the material used to make the rod
This was an overestimate, but by the time Newton wrote Principia, a number of astronomers had reproduced the result, and narrowed the transit time to 16 minutes. Considering that the distance from the Sun to the earth is 93 Million Miles, what do ..
