The deepest point in any ocean is in the mariana trench, which is about 11 km deep, in the pacific. the pressure at this depth is huge, about 1.13 108 n/m2. (take the bulk modulus of seawater to be 2.34 109 n/m2

Does work output exceed work input when a machine is used? a) yes, it does, as machines create energy. b) it depends on the type of machine used. c) no, it doesn’t, as machines are inefficient. d) no, it doesn’t, as machines cannot create energy.

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
