Answer
Can the wave travel between the Sun and Earth.
Explanation:
This would be due to the fact that mechanical waves alone require a medium to travel. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space. ... Mechanical waves require a medium in order to transport their energy from one location to another.
Answer:
There are several kinds of plants who grow and thrive near volcanic locations. For example coffee, grape vines, moss and the rare Hawaiian argyroxiphium, or "silversword." These plants grow and survive using the nutrients from the ashes of the volcanic eruptions along with cooled lava.
Mosses and Lichens form a protective layer over the land which helps it to retain water inside it, rather than drying out which is the case in volcanic sites. Therefore, the retained water helps the land to form and become appropriate for other plants to grow as well.
Answer:
Your answer will be C. 3.8 kPa.
Explanation:
Given that,
Number of slits per cm, 
The third fringe is obtained at an angle of, 
We need to find the wavelength of light used. The grating equation is given by :
, n = 3
So, the wavelength of the light is 400 nm. Hence, this is the required solution.
