Ahouse is maintained at 1 atm and 24°c, and warm air inside a house is forced to leave the house at a rate of 90 m3/h as a result of outdoor air at 5.5°c infiltrating into the house through the cracks. determine the rate of net energy loss of the house due to mass transfer. the gas constant of air is r

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
