The first line caries 30 microCoulombs per meter, and the second line caries 435 microCoulombs per meter. What is the magnitude of force that one meter of the first line receives from the second line. The lines are 10m apart. I really don't know how to start. Can someone please explain this question. Thanks.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

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.
