The emissivity of the human skin is 97.0 percent. use 35.0 °c for the skin temperature and approximate the human body by a rectangular block with a height of 1.96 m, a width of 41.0 cm and a length of 30.5 cm. calculate the power emitted by the human body.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
