A2.02 nf capacitor with an initial charge of 4.55 µc is discharged through a 1.22 kω resistor. (a) calculate the current in the resistor 9.00 µs after the resistor is connected across the terminals of the capacitor. ma (b) what charge remains on the capacitor after 8.00 µs? µc (c) what is the maximum current in the resistor? a

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton
