Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.46 m radius and is 2 m high. The walls are 1.0 cm thick. The thermal conductivity of Aluminum is 217 W/(m K). Assume that the temperature of the hot water inside the hot water heater is kept at a constant 90 C, and the external temperature is 27 C. How much energy is lost through the walls of the hot water heater in one week? (Assume thinner surface of the heater is 90 C and the outer surface is 27 C.)
Use the simulation in the cannon interactive in this section to answer the following questions. (a) Does cannonball's horizontal velocity change as it moves through the air? (b) Does its vertical velocity change? (c) If you enhance the cannonball's h..
A small plastic ball with a mass of 6.50 x 10?3 kg and a charge of +0.15uC is suspended from an insulating thread, What is the magnitude of the charge on each plate
You are so tired after studying that you leave all of these household devices turned on for 13.0 hours, Calculate the cost (in dollars) of the electric bill
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
The two stick together and move off with a speed of 4.0 m/s. Evaluate what is the mass of the second car?
A rope, assumed massless, is stretched horizontally between two supports that are 3.43 m apart. obtain the tension in the rope
Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity.
Starting from rest, you pull the string with a constant force F = 8 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance x = 0.12 m, a length d = 0.27 m of string has unwound off the disk.
A concave shaving mirror has a radius of curvature of 40.1 cm. It is positioned so that the (upright) image of a man's face is 2.7 times the size of his face. How far is the mirror from the man's face?
A pressure gage located 1 m off the bottom in 10 m depth of water measures an average maximum pressure of 10 N/cm2 having an average period of 9 sec
An x-ray tube accelerates electrons from rest at 5.0×10 14th m/s(squared) power through a distance of 20cm . (Such high accelerations are possible because electrons are extremely light.) Find the electrons'velocity after this acceleration. Find th..
