In a previous problem, you calculated how much energy was needed to accelerate a 2,100-kg tesla model s from 0 to 100 km/hr, and found that the value was not dependent on how long it took. however, the power is! unlike gas engines, electric engines supply equal power regardless of their speed. a tesla model s is capable of generating 345 kw of power. assuming no losses of energy to friction, what is the minimum length of time it takes to accelerate a tesla model s from rest to 100 km/hr?

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

Afrequency generator sends a 550 hz sound wave through both water and ice. what is the difference in wavelength between the wave produced in ice and the wave produced in water?

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.
