Suppose after charging a 4 µF capacitor to 8 V, you connect it to the second uncharged capacitor of 7 µF. What voltage will your voltmeter read across the second capacitor after repeating the charge sharing process three times? Express the answer with one decimal place.
Determine the amount by which the star's thermal radiation increases the entropy of the universe each second. Assume that the star is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K. Do not consider ther..
Starting in the spring, fruit begins to grow on the outer end of a branch on a pear tree. Define how the center of gravity of the pear growing branch shifts all through the course of the summer.
The electrons in a metal that produce electric currents behave approximately as molecules of an ideal gas. The mass of an electron is me = 9.109x10-31 kg. If the temperature of metal is 311 K, what is the root-mean-square speed of the electrons.
A 120 granite cube slides down a 45 frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 210 steel cube at rest.
