An object is inside a room that has a constant temperature of 292 k. via radiation, the object emits three times as much power as it absorbs from the room. what is the temperature (in kelvins) of the object? assume that the temperature of the object remains constant.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Which type of energy is transferred by convection currents?

How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 4.57×10−21 newtons?
