(a) What is the rate of energy loss in watts per square meter through a glass window 4.0 mm thick if the outside temperature is -15°F and the inside temperature is +80°F? (b) A storm window having the same thickness of glass is installed parallel to the first window, with an air gap of 6.2 cm between the two windows. What now is the rate of energy loss if conduction is the only important energy-loss mechanism? (The thermal conductivity of window glass is 1.0 W/m-K, and of air is 0.026 W/m-K.) (a) Number i Units (b) Number i Units

Earth's gravity pulls everything downward It pulls down each kilogram with a force of 9.8 Newtons. On a force table, a thread has a brass cylinder attached to it weighing 100 grams. If Earth's gravity pulls this weight (0.1 kg) downward with 0.98 N of force, how much weight is applied by Earth's gravity to the brass cylinder hanging on the thread?
