A fireman standing on a 9.1 m high ladder operates a water hose with a round nozzle of diameter 1.8 inch. The lower end of the hose (9.1 m below the nozzle) is connected to the pump outlet of diameter 3.1 inch. The gauge pressure of the water at the pump is(gauge) Plamp-P, tin 50.6 PSI 348.875 kPa (abs) pump atmCalculate the speed of the water jet emerging from the nozzle. Assume that water is an incompressible liquid of density 1000 kg/m^3 and negligible viscosity. The acceleration of gravity is 9.8 m/s^2 . Answer in units of m/s.

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
