The social media in Iran, in 2009, as well as after that, has mostly been used for propaganda. The freedom of the social media, thus the freedom of speech too, are very limited, almost non-existent in Iran. The government holds strongly the social media and it decides what can go through and what not, with the majority of the content being focused around the government and positives about it, showing the opposition in bad light, and even more, showing the enemies of the country is evil and that they constantly plot something against them.
Answer:
all of the above
Explanation:
obviously A
location is used on a map
C = building or roads
cartography is making maps
The high pressure in the Great Basin forces it way toward the lower pressure on the coast usually during the winter months. As the air sinks, it heats up, loses moisture, and increases in speed as it forces its way through the canyons. So, hot intense winds are the result. This also contributes to the forest fires in the area.
Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
