1. If a circle has a radius of five what is the diameter?

Seven

Five

Ten

Fifteen

Thirty

The diameter of a circle is always twice the length of its radius. Therefore, if the radius of a circle is five, the diameter would be 10.

Explanation

The diameter of a circle is always twice the length of its radius. Therefore, if the radius of a circle is five, the diameter would be 10.

2. What color is the sky?

Blue

Green

Red

Yellow

N/A

The sky appears blue because of a phenomenon called Rayleigh scattering. The Earth's atmosphere scatters shorter wavelengths of light, such as blue and violet, more than longer wavelengths like red and yellow. As a result, when sunlight passes through the atmosphere, the blue light is scattered in all directions, creating a blue sky. This is why we perceive the sky as blue during the day.

3. What galaxy are we in?

Nebulon

Sirris

Milkyway

The correct answer is Milkyway because the Milky Way is the galaxy that our solar system is a part of. It is a barred spiral galaxy that contains billions of stars, including our sun. The Milky Way is named after the band of hazy light that stretches across the night sky, which is caused by the collective glow of countless stars and other celestial objects.

4. Which star is hotter blue or red?

Blue

Red

Blue stars are hotter than red stars. The color of a star is determined by its temperature. Blue stars have higher temperatures compared to red stars. The hotter a star is, the more blue it appears. This is because hotter stars emit more energy at shorter wavelengths, which corresponds to the blue end of the visible light spectrum. Red stars, on the other hand, have lower temperatures and emit more energy at longer wavelengths, giving them a red appearance. Therefore, blue stars are hotter than red stars.
