7. Although tigers are not the fastest of predators, they can still reach and briefly maintain a speed of 55 km/h. assume that a tiger takes 4.1 s to reach this speed
from an initial speed of 11 km/h. What is the magnitude of the tiger's
acceleration, assuming it accelerates uniformly?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Which subatomic particle has a negative charge

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.
