g=9.81 and pwater(water density)= 1000kg/m^3
1)Assuming there are both a pressure gage and a manometer attached to a gas tank which has a pressure lower than Patm. If the reading on the pressure gage is 10kPa and atmospheric pressure is 100kPa, determine (a) the absolute pressure of the tank, and (b) the height of the fluid between the two fluid levels in the manometer, given the fluid is has a specific gravity of 1.5.
2) Calculate (a) the energy of a 1150-kg car consumes if it is driving at a velocity of 20m/s and a 100 m-long uphill road with a slope of 10°; (b) the power is will require if the car is accelerating from 2m/s to 10m/s in 0.5s on a flat road. Disregard friction, air drag, and rolling resistance.
