In fusion the mass of the products are less than the mass of the reactants. Why? does this mean energy is produced by fusion?
Why is the risk equivalent (or risk adjusted) spot rate less than the actual spot rate? Keeping in mind the expectations theory of term structure.
Some fish have a density slightly less than that of water, and must exert a force (by swimming) to stay barely submerged. Part (a) What force must a grouper of mass m exert to stay submerged in salt water of density ρw if its body density is ρf? Part (b) What is this force, in newtons, if the fish's mass is 82.5 kg, the density of the water is 1025 kg/m3, and the density of the fish's body is 1015...
