Consider a room that is initially at the outdoor temperature of 20°c. the room contains a 40-w light bulb, a 110-w tv set, a 300-w refrigerator, and a 1110-w iron. assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

It is really hard for me right know

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
