Answer:
Disadvantage
Explanation: It can become active anytime
Absolute magnitude measures only a star's luminosity.
It's a number that tells how bright a star would look if ALL stars were the same distance from Earth.
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.
Answer:
The Himalayan Mountains by India, Nepal, and China are the best example of a convergent plate boundary.
Explanation:
The Himalayan Mountains are the highest mountain range in the world, but also the most massive one. It acts as a natural boundary between Southern, Southeastern, Eastern, Central, and Southwestern Asia. This mountain range is a relatively young one (geologically speaking), and it has formed because of the collision between the Indian and Eurasian tectonic plates.
When India diverged from Gondwana, it started to move toward Eurasia. After tens of millions of years, the Indian plate hit the Eurasian plate from the south, and with both of the plates being continental and having a boundary with their continental parts, they created a convergent plate boundary. The pressure between the plates has resulted in lifting up the crust, gradually creating a huge mountain range.
