Answer:
Matter in its gas state has the most thermal energy than when it is a solid or a liquid. Because gasses have more thermal energy than others, they move differently than others.
Explanation:
;P
To develop this problem it is necessary to apply the concepts related to frequency from Hooke's law.
By Hooke's law we know that the Force is defined as
Where,
k = Spring constant
Displacement
at the same time Force can be defined by Newton's second law as,
F = mg
Where,
m = mass
g = gravity
Equating we have
Frequency and oscillation can be defined as
Then replacing,
Speed = distance / time
If you input your numbers into this equation you will be able to find the cyclists average speed
Answer:
2625 m deep
Explanation:
Let the sound speed in sea water be 1500 m/s. If he hears the echo 3.5s after the strike, then the sound would have traveled a distance of 1500 * 3.5 = 5250 m to the bottom and back. This would mean the ocean is 5250 / 2 = 2625 m deep.
