In extremely cold weather conditions where the inside thermostat is set to 27 C and the outside temperature is -20 C, your 1200 square ft house might lose heat through the walls at a rate of 4000 W. How much energy might you lose in one week? Electric heat can be 100% efficient. At 10 cents per kilowatt-hour how much would it cost to heat your house for one week under such cold conditions?
Sound with a frequency 700 Hz from a distant source passes through a doorway 1.07 m wide in a sound-absorbing wall. Find the number of the diffraction minima at listening positions along a line parallel to the wall
A point charge of -12 micro-coulombs is fired directly towards a single infinite sheet of charge. It is initially moving at 3.4 m/s towards the sheet and after it has traveled 0.7 meters it is moving at 18.4 m/s.
