Suppose a profit-maximizing firm in a competitive market produces rubber bands. when the market price for rubber bands falls below the minimum of its average total cost, but still lies above the minimum of average variable cost, in the short run the firm will: a. earn both economic and accounting profits. b. shut down. c. raise the price of its product. d. experience losses but will continue to produce rubber bands.

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?
