The concrete slab of a basement is 11 m long, 8 m wide, and 0.20 m thick. during the winter, temperatures are nominally 17°c and 10°c at the top and bottom surfaces, respectively. if the concrete has a thermal conductivity of 1.4 w/m · k, what is the rate of heat loss through the slab? if the basement is heated by a gas furnace operating at an efficiency of ηf = 0.9

Astudent looks at ocean waves coming into the beach. an ocean wave with more energy will a) have a greater height. b) have a greater period. c) travel toward the beach faster. d) strike the beach with greater frequency.

In 1980, alfa romeo introduced the first system to smooth a rough idle caused by ignition and camshaft timing changes.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
