You take a spacecraft that is capable of traveling an average speed of 70,811 km/hr (44,000 mi/hr) to the actual planet, while your friend drives a vehicle at an average speed of 112.7 km/hr (70 mi/hr) along the red line of the scaled solar system. Which answer below is correct

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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.
