A capacitor circuit: C1 and C2 are in series, C3 and C4 are in series, and these two collections 1-2 & 3-4 are in parallel with each other. C1 =1.00pF , C2 = 0.600pF, C3 = 3.20pF and C4 = 2.40pF. What is the total charge stored in the system if it is connected to a 5.07V power supply?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?

Ababy stroller is a rest on top of a hill which is 10 m high. the stroller and baby have a mass of 20 kg. what is the potential energy of the baby and stroller?
