Answer:
d. none of these
Explanation:
From the given information:
Let assume that Percival catches Sir Rodney's horse in time "t" after covering a certain distance "s"
Then, using the second equation of motion:
FOR Percival, we have:
FOR Sir Rodney;
Equating both equations together; we have:
0.3t² = 3t
0.3t² - 3t = 0
0.3t(t - 10) = 0
If Percival's position at rest = 0
Then; t = 10 s.
I'm sorry, but this is not a question. What do you need to know?
Time = (distance) / (speed)
Time = (4.12x10^16 m) / (3 x10^8 m/s)
Time = 1.37 x 10^8 seconds
Divide the seconds by 86,400 to get days. Then divide the days by 365 to get years.
Time = about 4.35 years
Answer:
The warmth you feel is the heat generated by the force of friction created by the rough surfaces of your hands rubbing together. As the abrasives in your eraser are rubbed against paper, friction produces heat, which helps the rubber become sticky enough to hold onto the graphite particles.

I hope this helps and pls mark me brainliest :)
When Object is at zero height, and there is no potential energy possess by the object then it exerts Greatest Kinetic energy in it's whole Journey
Hope this helps!
