When you turn on a fan its electrical energy changes into kinetic energy
Explanation:
This graph shows the acceleration of a racehorse taking off from the starting gate. By 27m/sin horse’s speed increase between 4 seconds and 6 seconds?
You're in luck ! Momentum is the product of (mass) times (velocity).
So if you're given mass and velocity, simply multiply them, and voila,
you have the momentum.

Explanation:
Answer:
B
Explanation:
<em>A. His speed is 0 m/s
</em>
<em>B. His velocity is 12 m/s
</em>
<em>C. His velocity is 0 m/s
</em>
<em>D. His acceleration is 12 m/s</em>
Total distance traveled by John = 120 + 120 = 240 meters
Total time taken by John to cover the distance = 10 + 10 = 20 s
<em>Average speed of John = total distance traveled/total time taken</em>
= 240/20 = 12 m/s
Hence, the average speed/velocity of John throughout the journey is 12 m/s.
The correct option is B.
