Answer :
Final answer:
The 143-lb concrete canoe displaces an extra 108 lbs of water compared to the 35-lb kevlar canoe, given they are of the same size and carrying the same cargo. This is due to the principle of buoyancy.
Explanation:
The question asks how much extra water a 143-lb concrete canoe displaces compared to a 35-lb kevlar canoe, If both have the same size and carry the same load. According to the principle of buoyancy, the amount of water displaced by an object is equal to its weight. Therefore, a 143-lb concrete canoe displaces 143 lbs of water, and a 35-lb kevlar canoe displaces 35 lbs of water. To find the difference between the two, subtract the weight of the water displaced by the kevlar canoe from the weight of the water displaced by the concrete canoe.
Thus, the concrete canoe displaces an extra 108 lbs (143-35) of water compared to the kevlar canoe of the same size carrying the same load. This is the extra buoyant force that the concrete canoe has over the kevlar canoe, essentially because it is made of a denser material.
