The unit for work J can also be written as Nm. Therefore, it is a derived unit as different SI units are needed to obtain its value. In this case, its derived from force and distance.
Well the basic equation for velocity is v=d/t where d is distance and t is time. So v=2m/50s and the answer is v=0.04meter/second.
Answer:
C
Explanation:
Opposites attract, the north pole of one of the magnet is attracted to the south pole of the other magnet. Two north or south poles will repel away from each other.
<h3>Speed between point A and B</h3>
= Total Distance/Total time
= 30/3
= 10 km/h
<h3>Average speed for this ride</h3>
Average speed = Total distance travelled/time taken
= 50/6
= 8.3 km/h
