Average speed is worked out from dividing distance by time.
Answer:
I think it's how far out the water goes from the beach before the tsunami because before tsunami usually the water goes back way behind the tide before tsunami and that tells them everything they need I think
Answer:
Not quite
Explanation:
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength
What determines the strength of a wave?
Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.
So,
As Wavelength increases, The energy of the wave spreads and it decreases
Answer:
Force, F = 44 N
Explanation:
Given that,
Initial speed of the football, u = 0
Final speed, v = 15 m/s
The time of contact of the ball, t = 0.15 s
The mass of football, m = 0.44 kg
We need to find the average force exerted on the ball. It is given by the formula as :

So, the average force exerted on the ball is 44 N. Hence, this is the required solution.
Answer:
There are 4 liquids in this experiment and red is the least dense of all of them so it should float on top, which it is doing.
The red that you see at the bottom is neither liquid nor is it a part of the experiment.
It is simply the <u>color of the bottom of the container</u> that the experiment was conducted in.
