1. As of right now, our solar system only includes asteroids and they are found in Kuiper Belt next to Saturn.
On May 6, 2020, scientists have discovered a mysterious blanket of darkness approximately 1,000 light years away from our solar system. However, in this case, black holes would not be a correct answer.
Even though constellations may seem close, they are actually far away since the size of the stars are immense and can be visible from light years away. Constellations are not in our solar system.
Galaxies are groups of solar systems so therefore galaxies is not an answer.
2. Ptolemy was the man who proposed the early Earth-centered model of the universe and his model was called the Ptolemaic model also known as the geocentric model.
3. The planet that is most similar to Earth in mass and diameter is Venus.
4. The inner planets in our solar system are formed from dense elements and that is why they are able to withstand the intense of the sun. Meanwhile the outer planets were formed from gaseous materials but Pluto is so cold that its elements are hardened and dense.
5. The answer would be D since they orbit in the same direction and on the same plane.
6. The speed of rotation determines the length and duration of day on a planet.
7. The answer would be D since they have to have their own gravity, have a path clear of smaller bodies , and orbit a star,
Answer:
Q = M * (Cf + C * 100 + Cv)
Cf and Cf are heats of fusion and vaporization and C is the heat required to heat mass M of water 1 deg
Q = .001 kg ( 3.36 * E5 + 100 deg * 4200 + 2.26 * E6) J
Q = .001 kg ( 3.36 J / kg + 4.2 J / kg + 22.6 J /kg) * 10E5
Q = .001 kg * 30.2 * 10E5 J / kg = 3020 J
Answer:
D. Improving their design to make it easier to recycle them when they are no longer useful.
Explanation:
Just took the test on (APEX)!!
Answer:
C. position
Explanation:
potential energy is based on stored energy, therefore it is C
Answer:
They're are useful in providing larger frictional force
Explanation:
The football shoes have spikes or studs because the studs or spikes provides larger frictional force than normal shoes while running on the grass.
The studs helps to prevent a player from slipping on the grass and help to run faster and change direction quickly without slipping.
