Question

Some fish have a density slightly less than that of water and must exert a force (swim) to stay submerged. What force must an 85.0 -kg grouper exert to stay submerged in salt water if its body density is 1015 $\mathrm{kg} / \mathrm{m}^{3} ?$

Name: some fish have a density slightly less than that of water and must exert a force swim to stay submerged what force must an 850 kg grouper exert to stay submerged in salt water if its body density is 2

Step 1

Given that the density of salt water is 1015 $\mathrm{kg/m}^{3}$ and the mass of the fish is 85.0 kg, we can use the formula $volume = \frac{mass}{density}$ to find the volume of water displaced by the fish. $volume = \frac{85.0}{1015} = 0.08375 \mathrm{m}^{3}$ Show more…
