I need help on physical science At what temperature (in oC) would the volume of a gas be equal to 45.7 L, if the volume of that gas was 33.9 L at 12.4oC?

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

How is zig zagging a form of acceleration?

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
