work = force x distance
10N and 4m gives 40 joules
Answer:3.71 m/s
Explanation:
Given
square track with sides 50 m
average speed is 5 m/s
Total running time=53.8 s
Total distance traveled in this time
i.e. Person has completed square track one time and another 69 m in second round
So displacement is 269-200=69 m
average velocity

Difference between average velocity and average speed is
5-1.28=3.71 m/s
Answer:
B on edge
Explanation:
the piles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnent. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin
The AU ... Astronomical Unit ... used to be defined as the average distance between the Sun and Earth during the year.
Now it's defined as 149,597,870,700 meters exactly.
I believe the answer would be elastic because you are pulling the sting of the bow back.
hope this helps :)
