QUESTION:
Rank the buoyant forces supplied by the atmosphere on the following, from greatest to least:
a. An elephant
b. A helium-filled party balloon
c. A skydiver at terminal velocity
ANSWER:Step 1 of 3
The buoyant force is equal to the weight of the displaced fluid, which is air. We don't need to make any calculations; a little common sense should suffice. We must first determine which of the items on the list above is the largest or has the highest volume if we displace fluid simply by existing. The elephant should be there. It should be the skydiver if you do it again. It should be the balloon if you do it again.
