Uhhh help lolz For the following situations, determine whether the sound amplitude is large or small and whether the frequency is high or low. For example, when the fat lady sings at the opera, she’s famous for making a high frequency, large amplitude sound. Describe
The thumping base on a car stereo
The squeak of a mouse
The sound of distant thunder
The screech of brakes

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.
