Question: Lightbulb A is marked "40.0 W 120 V," and lightbulb B is marked "60.0 W 120 V." These labels mean that each lightbulb has its respective power delivered to it when it is connected to a constant 120-V source.
(a) Find the resistance of each lightbulb. R(40.0 W 120 V) = R(60.0 W 120 V) =
(b) During what time interval do 2.00 C pass into lightbulb A?
(c) Is the charge different upon its exit versus its entry into the lightbulb? Explain.
(d) In what time interval do 1.70 J pass into lightbulb A?
(e) By what mechanisms does this energy enter and exit the lightbulb? Explain.
(f) Find the cost of running lightbulb A continuously for 30.0 days, assuming the electric company sells its product at $0.110 per kWh.

One of the conditions for Uniform Circular Motion is that the acceleration be centripetal and directed toward the center of motion. Explain what would the effect be of non-zero acceleration parallel to the tangential velocity
A 0.50-kg mass attached to the end of a string swings in a vertical circle (radius = 2.0 m). When the string is horizontal, the speed of the mass is 8.0 m/s. What is the magnitude of the force of the string on the mass at this position?
Proton one moves twice as fast as proton two. The magnitude of the magnetic field in which proton one is immersed is twice the magnitude of the magentic field in which proton two is immersed.
