Assume that a 0.80 m length of wire carries a current at right angles to a 1.87 T magnetic field. The force on the wire is 12.0 N. What is the current in the wire?

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

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.
