The third one because it is a small one and it had high and high temp so it has the most modecules.
Hope this helps
Explanation:
Below is an attachment containing the solution.
60 N because 98N=mg (here g= 9.8 on earth) thus mass can be calculated which is 98/9.8 = 10kg
Now,new weight with g = 6m/s^2
=m×g' (here g' is new acceleration of the new planet)
= 10×6=60N
Answer:
Thus, average speed of the sprinter is 0.5854
.
Given:
Total distance = 200 m = 0.2 km
Total time = 20.5 second =
hour = 0.3416 hour
To find:
Average speed = ?
Formula used:
Average speed = 
Solution:
Average speed of the sprinter is given by,
Average speed = 
Average speed = 
Average speed = 0.5854 
Thus, average speed of the sprinter is 0.5854
.
