If a net force of 250 n causes an object to accelerate at 20m/s^2 what must its mass be?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

1. a camcorder has a power rating of 19 watts. if the output voltage from its battery is 7 volts, what current does it use?answer units 2. a 1.5m wire carries a 6 a current when a potential difference of 57 v is applied. what is the resistance of the wire? your
