Average Speed = 23.33 m/s
<u>Explanation:</u>
Given:
Diameter = 7 km
So, to find the distance, we need to multiply it by 10 as the race car circles 10 times round this 7 km track.
Distance = 7 × 10 = 70 Km or 70,000 m
Time = 50 mins
= 50 × 60 = 3000 s
Now, in order to find the average speed for 10 cycles, we use the formula:
So by substituting the above values in the given formula, we get:
Speed = 23.33 m/s
Total amount of energy would remain constant according to law of conservation of energy. i.e., 50 Joules
In short, Your Answer would be Option C) <span>50 Joules because as energy converts from one form to another, it cannot be created or destroyed during the conversion.

Hope this helps!
If you could please give me a already given speed I could estimate it. since there is no speed shown you wouldn't be able to estimate the speed of the moving train.
The reasoning which is in use when large, angular rocks are interpreted to have originated from the outcrop at the top of the hill is; Fossil succession
<h3>Fossil succession of rocks</h3>
The principle of fossil succession in characterized by the fact that fossil entities succeed one another upward through rock layers in a definite and determinable order.
On this note, any time period can be dated by its fossil content.
