In the increasing size order, they are Universe, Andromeda galaxy, solar system, Arcturus, Sun, Earth.
- The universe, cosmos contains all things. It has countless billions of galaxies.
- The Andromeda Galaxy, together with the Triangulum Galaxy and about 30 other smaller galaxies, is the largest galaxy in the Local Group, which also contains the Milky Way.
- A solar system comprises a star and all its planets, asteroids, comets, and other celestial bodies. It is considerably bigger in the universe, cosmos than a star.
- Arcturus is a huge red star in the Northern Hemisphere of the Earth's atmosphere. When the sun has evolved into a red giant, it will look like Arcturus. Arcturus has a diameter that is roughly 25 times greater than the sun and earth.

Answer: Los Angeles.
Explanation: We know that the businessman is from Los Angeles, and we also know that the flight from Madrid to New York, so it is safe to say that the man is currently in the city of Madrid, in Spain.
Then, after the flight, he will be in New York, and from there hey may take a train to return to his home, so the city in which he gets off from the train maybe Los Angeles, where he lives.
The baseball because it has a greater mass and would go farther because it don't have holes for the air to go through and slow it down
Answer: 0.22
Explanation: Subtract 0.01kg from 0.23kg
Answer:
35.71 m
Explanation:
Potential energy is calculated using this formula:
- PE = mgh
- where m = mass (kg). g = gravitational acceleration on Earth (9.8 m/s²), h = height (m)
We are given 3 out of the 4 variables in this problem. We want to solve for h, the height of the cannon ball.
List out the known variables:
- PE = 14,000 J
- m = 40 kg
- g = 9.8 m/s²
- h = ? m
Substitute these values into the potential energy formula.
- 14,000 = (40)(9.8)h
- 14,000 = -392h
- h = 35.7142857143
The cannonball was 35.71 m high to have a potential energy of 14,000 J.
