Answer:
Kindly check explanation
Explanation:
According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.
Answer:
The different speed of the sound waves in water and in air.
Explanation:
Sound waves are defined as the mechanical waves that are resulted from the vibrations back and forth of the particles of the medium through which the sound is moving.
The speed of the sound is faster in water than in air. Sound travels much faster in water than in air. In air the speed of the sound waves is 343 meter per second while the speed of the sound waves in water is 1480 meters per second.
In the context, Jason who is swimming in his pool hears sound differently underwater and above the water because of the difference in the speed of the sound waves above the water and in water.
There is no picture shown, however details like this indicate that Scientist are examining the future changes in biodiversity within the Hudson river. If vegetation would see a continuous decrease, animals are forced to flee their habitat and find new areas or locations where they could thrive. When this happens, changes in the environment would put a great deal on the existence of certain forms of species within the area.
<span>Another name for a fertilized egg is a zygote. The correct option among all the options that are given in the question is the last option or the fourth option. The other three options given in the question is not correct and can be avoided. I hope that the answer has come to your help.</span>
To calculate this we will use the light equation:
λ
We have Frequency
.
We know that speed of light in vacuum is
.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

λ

⇒ λ
⇒ <span>λ</span>
