Consider a rectangular tank with height 5 m and base 4 × 8 m^2. Suppose the tank is half full of water. Find the work required to empty the tank through a whole at the top of the tank. The density of water is 1000 kg/m^3 and g = 9.8 m/s^2.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
