1. Un automóvil tiene una aceleración muy alta. Partiendo del reposo, su velocidad puede, en promedio, aumentar 7.31 m/s cada segundo, hasta alcanzar el valor de 27.8 m/s, equivalentes a 100

km/h.

a) ¿Cuánto tiempo necesita para alcanzar la velocidad de 100 km/h, partiendo del reposo?

b) Suponiendo que su aceleración es constante, ¿qué distancia recorre en este movimiento

acelerado?

c) ¿Puedes decir, sin hacer ningún cálculo, qué parte de la distancia calculada en b) ha recorrido el

automóvil hasta el momento en que su velocidad era de 50 km/h?

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.
