If the coolant in an air conditioner has a higher temperature than the air in a building, then a. heat will flow from the air into the coolant b. no heat flow will take place c. heat will flow from both the coolant and the air d. heat will flow from the coolant into the air

Heat will flow from the coolant into the air.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

could i give you a exaplo that could you?
