What is the outward force on the sidewall due to the air pressure? F = P * A We need the answer in N. So, P is in Pascals which we can figure Pa = 84 psi * 6890 Pa = 578760. A is area in meters 2 which can be done through the conversion m 2 = 1600 in 2 * 1550.0031 = 1.032256 m 2 2. A small statue is recovered in an archaeological dig. Its weight is measure to be 211.2 lb and its volume 0.176 ft3. (a) What is the statue’s weight density? (b) What substance is it? D W = W/V which is the weight density of gold. 3. A large tanker truck can carry 30 ton (30,000 lb) of liquid. (a) What volume of water can it carry? (b) What volume of gasoline can it carry? Water weights 8.35 lb/gal and Gas weights 6.42 lb/gal. 4.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
