A13.1 î¼f capacitor is connected through a 853 kî© resistor to a constant potential difference of 64 v. compute the charge on the capacitor at 14 s after the connections are made. (give your answer in decimal using micro c (î¼c) as unit)

An implanted pacemaker supplies the heart with 72 pulses per minute, each pulse providing 6.0 v for 0.65 ms. the resistance of the heart muscle between the pacemaker’s electrodes is 550 ω. find (a) the current that flows during a pulse, (b) the energy delivered in one pulse, and (c) the average power supplied by the pacemaker.

Aproton is projected toward a fixed nucleus of charge +ze with velocity vo. initially the two particles are very far apart. when the proton is a distance r from the nucleus its velocity has decreased to 1/2vo. how far from the nucleus will the proton be when its velocity has dropped to 1/4vo?

Atomic nuclei of almost all elements consist of
