    1. A solid uranium cylinder weighs 91.53 N in air and 86.63 N when submerged in water.

    a. The volume of the cylinder is ----------mt^3
    b. The density of uranium is---------kg/mt^3

    2. On each heartbeat,about 70 cm^3 of blood is forced from a human heart at an average pressure of approx 105 mm Hg.

    a. If the heart beats 70 times per minute, the average power output of the heart is ---------- watts.

    1. A solid uranium cylinder weighs 91.53 N in air and 86.63 N when submerged in water.

    a. The volume of the cylinder is ----------mt^3

    b. The density of uranium is---------kg/mt^3

    Solution: We have the following formula for measuring relative density,

    where, W is the weight of uranium in air and F is that when submerged in water.
    G = 91.53/(91.53-86.63)
    = 91.53 / 4.9
    = 18.6796
    So we have the relative ...
