15. during a power shutdown a room is losing thermal energy at a rate of 1.0-kw due to heat transfer through its walls to the street. find the increase of entropy of a "mini-universe" (the room and the street) during 1 hour, assuming the temperature of the room +20°c does not change noticeably during this time, while temperature in the street outside remains -10°c. a) 1.40 kj/k b) 0.89 kj/k c) 1.68 kj/k d) 1.96 kj/k e) 2.24 kj/k

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
