The main water line enters a house on the first floor. the line has a gauge pressure of 1.57 x 105 pa. (a) a faucet on the second floor, 7.00 m above the first floor, is turned off. what is the gauge pressure at this faucet? (b) how high could a faucet be before no water would flow from it, even if the faucet were open?

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.
