(20 points) A water truck's tank has internal dimensions of 12 meters in length and 1 meters in diameter. If the truck's load of pure water is 70 percent of full capacity, how heavy is the load in pounds? Water's density is 62.4 lb/ft3 lbs In kilograms, what is the weight of the load if the truck carries liquid nitrogen instead of water? The liquid nitrogen's density is 0.808 g/ml. kg

A person who has a weight of 161 pound-force [lbf] on Earth is travelling to Mars in a spacecraft. As long as the engines on the spacecraft are not operating, the person is essentially weightless during the voyage. During a course correction, the spacecraft undergoes an acceleration of 0.68 g. The term "g" is the Earth-normal gravity, so 1 g is 9.8 meters per second squared [m/s2]. This acceleration makes it feel like there is gravity in the spacecraft, and...

The answer above is NOT correct. (1 point) A gas station stores its gasoline in a tank under the ground. The tank is a cylinder lying horizontally on its side. (In other words, the tank is not standing vertically on one of its flat ends.) If the radius of the cylinder is 0.5 meters, its length is 8 meters, and its top is 2 meters under the ground, find the total amount of work needed to pump the gasoline out...

A physics lecture room has a volume of 248 m3 . Part A For a pressure of 1.00 atm and a temperature of 26.0 ∘C, use the ideal-gas law to estimate the number of air molecules in the room. Assume all the air is N2. Part B Calculate the particle density-that is, the number of N2 molecules per cubic centimeter. Express your answer to three significant figures and include the appropriate units. Part C Calculate the mass of the air...
