it is from under the earth's surface. There are under the surface streams that create springs
It is precipitation that fell on the ground and seeped down to a layer of rock. The water comes from an aquifer that is under the ground.
Answer: (A) The number of waves that pass a point in a certain amount of time.
Explanation:
Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm.
Frequency: Is the number of waves that pass a certain point in a specified amount of time.
Trough: The low point of the wave cycle.
Wavelength: The distance between two successive peaks.
Electromagnetic wave: One of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity.
D: An electromagnet with 20 coils.
That is because the more coils of the wire, the stronger the electromagnet is.
Answer: a. To control all of the people in the community
Explanation:
The sport organization help in bring people of different communities together. It removes any kind of discrimination based on caste, gender, race, and others.

The sports activities are recreational in nature, they build social interaction between people of different communities, control good health, make communities safer.
Answer:
The blue light
Explanation:
Spectrums of visible light with longer wavelength are absorbed more quickly such as red than those with shorter wavelength. This contributes to why blue with higher energy and shorter wavelength is able to penetrate deeply compared to others that are easily absorbed. Blue light persist longer so it reaches the depth first while so of others are absorbed.
