Suppose a cylindrical habitat in space 6.80 km in diameter and 24 km long has been proposed. such a habitat would have cities, land, and lakes on the inside surface and air and clouds in the center. this would all be held in place by rotation of the cylinder about its long axis. how fast would the cylinder have to rotate to imitate the earth's gravitational field at the walls of the cylinder? answer in rad/s.

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.
