Which of the following would be considered a current? a negative ions flowing in a liquid b electrons moving in a vacuum c positive ions flowing in a liquid d electrons moving in a wire e ions moving in a vacuum I presume all of these would be electric currents after reading this...

the image shows my response just minutes ago. you can see it gave me credit for my response. (my response in green) the check mark is just in a weird spot, that's not the answer. thanks for your efforts.

Here it is...

I think I've got it. The objects have to have the same mass in order to have equal heat capacity. The objects have to have the same temperature to be in thermal equilibrium. If there heat capacity and thermal equilibrium are identical, their internal energy will be the same.

I will have two lectures on thermodynamics in the coming week. I'm trying to complete online homework and can't find a good source of information for this question.

Yes, ground zero. I am leaning towards mass and temperature as the answer to the question.

Dick, I have no clue what "strategy" to go with, that's the whole reason I'm here.

What must be true for two objects of the same material to have the same internal energies? (Choose all that apply) a. The masses of both objects must be equal b. Both objects must have the same density c. The temperatures of both objects must be equal d. Separate objects cannot have...

Question about internal energies... PLEASE HELP ME! What must be true for two objects of the same material to have the same internal energies? (Choose all that apply) a. The masses of both objects must be equal b. Both objects must have the same density c. The temperatures of both...
