Answer:
Radiation waves (From the sun)
If the solar system were placed to the edge of the galaxy, the majority of the night sky would be black with few stars.
<h3 /><h3>What is Galaxy?</h3>
A galaxy is a collection of stars, stellar remnants, interstellar gas, dust, and dark matter that is gravitationally bound. The name comes from the Greek word galaxias, which translates to mean "milky" and refers to the Milky Way galaxy, which houses the Solar System.
Because stars are more prevalent near the galaxy's core and less at its extremities, if the Sun and Earth were transported to its edge, we would observe mostly black skies at night and few stars.
We may thus draw the conclusion that if the solar system were transferred to the edge of the galaxy, the most of the night sky would be black with only a few stars.

Hydrogen peroxide can cause hair loss, dermatitis and scalp burns.
Concerning the harmful chemicals in dyes, many people consider it is best to use henna if you really want a colour change for your hair.
Answer:
E = 10078.32 J
Explanation:
Given that,
The weight of a window cleaner, F = 839.86 N
The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.
We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :
E = mgh
Put values,
E = 839.86 × 12
E = 10078.32 J
So, the window cleaner will have 10078.32 J of potential energy.
The correct answer is Solar systems
Astronomy deals with studying the cosmos and everything that encompasses it such as stars, planets, meteors, asteroid, satellites, and similar.
