A 13.1 k? resistor and a capacitor are connected in series and then a 12.0 V potential difference is suddenly applied across them. The potential difference across the capacitor rises to 5.58 V in 1.95 µs.
(a) Calculate the time constant of the circuit.
(b) Find the capacitance of the capacitor
A small metal ball is given a negative charge, then brought near (i.e., within a few millimetres) to end A of the rod. What happens to end A of the rod when the ball approaches it closely this first time.
the volume of a gas is decreased by a constant external pressure of 0.200atm, changing from 2.10 litters to 0.58 litters. during this compression
An isotope of phosphorus called P-32 is radioactive. It decays with half life of 14.3 days with the emission of beta particle. A 1.0 m?Ci source of P-32 is implanted in a tumor where it would deliver radiation dose of 28.6 Gy.
A 12 kg weather rocket generates a thrust of 250 N. The rocket, pointing upward, is clamped to the top of a vertical spring. The bottom of the spring, whose spring constant is 560 N/m, is anchored to the ground. What is the rocket's speed while the s..
Two identical small insulating balls are suspended by separate 0.23-m threads that are attached to a common point on the ceiling, Determine the charge on each ball
Find out the magnitude and direction of the velocity of the heavier fragment relative to the ground just after the explosion. Please provide step-by-step method to solve the problem.
Coherent light with wavelength 595 nm passes by two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.84 {rm mm} from the center of th..
What is the force on a test charge Q at the center.
A spectral line from the left side of Saturn's rings, as you see them, is at a wavelength slightly shorter than the same spectral line measured from the right side of Saturn's rings. Which way (direction) is Saturn rotating and why?
A spool of thread has an average radius of 1- cm. If the spool contains 62.8 m of thread, how many turns of thread are on the spool.
(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 11.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) Imagine adding electrons to the pin until the negative charge ha..
If a power plant burns coal at 1000°C and the air temperature where the exhaust fumes cool is at 20°C, what is the maximum efficiency of the power plant?
