Document Summary
What happens to the brightness of lightbulb 1 when the switch s is closed: the brightness increases, the brightness remains the same as before the switch is closed, the brightness will decrease momentarily then return to its previous level, the brightness will increase momentarily then return to its previous level, the brightness decreases, a capacitor of capacitance c is made of two cylinders of radii a, and b ( b > a) carrying a linear charge density. What is the capacitance of a cylindrical capacitor with the same charge density , and cylinders of radii 2b and 2a: 2c, c/4, c/2, 4c, c, a charged particle is moving with speed v perpendicular to a uniform magnetic field. The frequency of revolution of the first particle is f. the frequency of revolution of the second particle is: f/4, 2f, f/2, f, 4f.
