An air compressor intakes atmospheric air at 14.7 psi and increases its pressure to 150 psi (gauge). The pressurized air is stored in a horizontal tank. What is the absolute pressure of air inside the tank? Express your answers in: (a) psi, (b) kPa, (c) bar, and (d) standard atm (recall that 1 atm =14.7 psi = 101.325kPa).

Which of the following describes something an engineer would probably do first when developing new technology meant to reduce ocean pollution? o a. evaluate the benefits and challenges of using certain chemicals to purify water. o b. research new scientific findings in regard to ocean cleanup. o c. identify the need to reduce ocean pollution. o d. research what has been done in the past to clean up oceanic oil residue.

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.
