Suppose you make your living fishing for lobster. You and everyone else are free to set out as many traps as you like. As more and more traps are set up, however, fewer and fewer lobsters are caught. Soon, lobster catches are too small to support your families. A meeting is coming up where you and your fellow lobster fishers will present possible solutions to this problem. What will you propose to combat this tragedy of the commons and restore the fishery?

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

2b2t

explanation:

2b2t

elements make up everything, and they combine to make compounds.

the answer is c

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
