2. If a 6.2A current flows through a 3.90 resistor, how much voltage is supplied? a. 20.18V
b. 1.58V
C..18V
d. 24.18V

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

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)

Can you match these to the correct definition
