Boyle's Law: P₁V₁ = P₂V₂
So (25 kpa)(0.21) = (2.5 kpa) V₂
(25 kpa × 0.21)/ 2.5 kpa = 2.1
2.1 = V₂
Momentum is conserved when you pull one ball bearing back in the air before letting it go to hit the others. Think about it. You lift the bearing in the air with all it's weight, thus leading it to build up momentum and conserve it. Then once you release it, it transfers the energy through the other bearings and out onto the other side repeating it's process.<span />
It is Hexane: C6H14
Hexane is a colorless liquid that is made from crude oil.
Answer:
This question is asking to find the average speed during the dive. The answer is 22m/s.
Explanation:
Average speed of a substance can be calculated knowing it's distance over a particular amount of time.
The formula for average speed is:
Average speed (s) = Distance (d) / time (t)
In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;
Average speed = 176/8
Average speed = 22
Therefore, the average speed of the falcon diver is 22m/s.
