Ishani and john now try a problem involving a charging capacitor. an uncharged capacitor with c = 6.81 μf and a resistor with r = 5.8 105 ω are connected in series to a 12.0 v battery. the switch is closed at time t = 0, allowing the capacitor to charge. find the maximum charge on the capacitor and the maximum current through the resistor.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
