Consider a long, closely wound solenoid with 10,000 turns per meter. what current, in amperes, is needed in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the earth’s magnetic field of 4.95 × 10-5 t?

What belongs in the areas marked x and y? x: the internal energy of a piston system increases as heat is added and rises to a cool area y: as thermal energy is added to a container, some of the energy is lost to the environment x: as thermal energy is added to a container, some of the energy is lost to the environment y: the internal energy of a piston system increases as heat is added and rises to a cool area x: a cold spoon placed in hot liquid gets warmer y: thermal energy is converted to light energy x: thermal energy is converted to light energy y: a cold spoon placed in hot liquid gets warmer
