Answer:
The true statement is:
d. It is impossible to know which contains more energy.
Explanation:
In this scenario, the frequencies of Photon A and Photon B were not given. This makes it impossible to know which photon contains more energy than the other. Note that the amount of energy is directly proportional to the photon's electromagnetic frequency but inversely proportional to the wavelength. A description of the associated wavelengths was offered, but this description is not enough to help determine the energy of each photon. In conclusion, the photon's frequency determines its energy level just as the wavelength reduces its energy.
To change the equation, you'd have to take the square root of both sides. When you do this, x^2 cancels out leaving you with x = sqrt(y)
If you need help on the other ones, all you have to do is solve for x by using either addition/subtraction or dividing/multiplying.
Answer:
Afghanistan's mountains have kept the country from ever being invaded.
Explanation:
Afghanistan is a country in terrible conditions, and this is not the case just nowadays but it has been like that for a very long time. Despite all of the internal troubles of the country and it seems to be very weak in pretty much every sector, it has never been invaded in the past few centuries, and very rarely in the more distant history and always it has been short-lasting.
The main reason for this has been the mountains and the general geography of the country. Very high and rugged mountains are separating the country from potential invaders. Even if an invading force manages to go through the mountains, it will suffer great losses just by doing so, and what comes next is desert and more rugged terrain, which will further damage them, so by the time they engage in battle, they will be too weak to conquer Afghanistan.
Answer:
In the sentences provided we can take an example of geographic space the following sentences:
- <u>West Africa is a geographic region on the continent of Africa.</u>
- <u>Chloe lives in a suburb west of Houston, Texas.</u>
Explanation:
Both sentences are making mention to a physical space organized by society, this is the concept of Geographical Space.
