Acceleration = (change of speed) / (time for the change)
Change in speed = (22 - 4) = 18 m/s.
Time for the change = 3 sec.
Acceleration = 18/3 = 6 m/s per second.
I think A but I dont really know
<span>In order to
change power, current or voltage should also be changed. Voltage is an
electromotive force, and also the quantitative expression that shows the
potential difference of the two points charged in an electrical field. So, before power will take place, it would
always be best to change also the voltage.</span>
Answer:
I'm not sure if the directions affect the speed tho
but I think it's 4? cause it's the speed relative to the ground
hope this helps:))
Answer:
D. A lower Voltage into a higher
