Consider two hosts, A and B, connected by a single link of rate ( 3x108 ) bps. Suppose that the two hosts are separated by 200 meters, and suppose the signal travels at ( 2x108 ) meters/sec along the link. Host A is to send a packet to host B. If the propagation time from A to B equals the transmission time of this packet, what is the packet size?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
