Answer:

Methods are given below.

Explanation:

1. Direct Imaging: Its directly seeing the planet itself, it's potential has increased dramatically over the past few years due to advancements in our technology.

2. Astrometry: Study of precise positioning of stars in the sky. The star is always much more massive than the planet, so the center of mass is much closer to the star, and thus the star's orbit is very tiny while the planet's orbit is much more pronounced.

3. Doppler Shift (also known as the radial velocity method) this method is based on the theorem that planet orbiting the stars have the same weight. The changes in the star spectrum and wavelength shows the brightness coming from the orbiting star.

4.  Pulsar Timing: This Is a time-bound approach to finding the planets that orbit the stars through the beam of light that the old star emits.

Explain how solar energy and wind energy are generated?​
nalin [4]

Answer:

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.1

Explanation:

wind energy, form of solar energy that is produced by the movement of air relative to Earth's surface. This form of energy is generated by the uneven heating of Earth's surface by the Sun and is modified by Earth's rotation and surface topography.

The climate in northern Russia determines the vegetation is mostly<br> what?
OLga [1]

The climate in northern Russia determines the vegetation to be of tundra type.

Explanation:

Northern Russia is on a very high latitude, and very close to the North Pole. Because this area receives very little and very scattered sunlight, it is very cold for most of the year. That has resulted in the area being frozen for most of the year, the growing season to be very short, and the soil quality very poor.

The vegetation that exists here has had to develop special adaptations because of the extreme conditions. It is vegetation of tundra type. This vegetation is usually very small, from few mm to few cm. The requirements for nutrition are very low, with very small roots, and adaptations on the surface to prevent water evaporation and freezing. Such plants are:

  • mosses
  • lichens
  • dwarf shrubs
  • sedges
  • grasses

How did the language of Quechua spread throughout the Andes?
Georgia [21]
We can immediately reject option D - while Spanish is an Indo-European language, Quechua is an indigenous language of the Americas. 

The Spanish conquerors did not care much about the indigenous population - except if they could covert them, which would make them be seen as defenders of the Christian faith and win them favours with the Pope. 

So they would not teach the indigenous population in secular schools, they would however, try to teach them religion. The correct answer is A - The Catholic clergy believed that Christianity would be adopted faster if translated into an indigenous language.
