A wire 43.7 cm long carries a 0.450 A current in the positive direction of an x axis through a magnetic field with an x component of zero, a y component of 0.000360 T, and a z component of 0.00830 T. Find the (a) x, (b) y, and (c) z components of the magnetic force on the wire.

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

Plss anybody know how to do this? ? i need the answers from a through d

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
