Jeff's body contains about 4.97 l of blood that has a density of 1060 kg/m. approximately 45,0% (by mass) of the blood is cells and the rest is plasma the density of blood cells is approximately 1 125 kg/m, and about l % of the cells are white blood cells, the rest being red blood cells. the red blood cells are about 7.50 pum across (modeled as spheres). what is the mass of the blood mblood in jeffs body? mblood- kg approximately how many blood cells (of both types) n are in jeff's blood?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?
