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.

What two obstacles do less developed countries face? How do they approach development?
Kaylis [27]

Answer:

<em>Developing countries two major issues, of low incomes and eventually lower tax collections.</em>

Explanation:

Obstacle 1: Developing countries usually have a population with a low income. There are a lot of poor people, very few businesses are documented and there are very few well established larger corporations.

Obstacle 2: Lower income results in a low tax collection for the country. This means that the government is not able to meet its basic infrastructure resulting in underdeveloped health facilities and basic infrastructure.

In order to improve this, they look for either foreign direct investment into their country or take out loans from international banks to fund basic needs.

If done well, countries can escape from poverty. However if loans are mismanaged, countries can quickly find themselves burdened with rising debt and more poverty.
