Most often those smaller structures are triangular in shape because triangular shapes are very strong and stable
Find the average speed and the average velocity.
Average speed = distance / time
distance = 10 x 8000 m = 80,000 m
time = 20 min * 60 s/min = 1200 s
Average speed = 80,000 m / 1200 s = 66.67 m/s
Average velocity = displacement / time
Given that the race car made complete circles the final poin is the same initial point, then its displacement is zero and the average velocity is zero too.
It defines that if two thermodynamic systems are each in equilibrium with a third system, then they are in equilibrium with each other.
