The solar system is bounded together by gravity, and is made up of the Sun  eight planets and dwarf planets

The correct options are;

  • The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
  • Earth ⇒ has a single moon that is surprisingly large compared to its planet
  • Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
  • Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
  • Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
  • Uranus ⇒ has an axis tilt that gives it very extreme seasons
  • Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
  • Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
  • Jupiter ⇒ has a famous storm known as the Great Red Spot
  • Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
  • Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world

Reasons:

The Sun generates energy by nuclear fusion in its cores

The size of the Moon more than a quarter of the Earth's size

Saturn moon Titan shows signs of volcanic activity

The moon Triton rotates in the opposite direction to the rotation of Neptune

Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter

Uranus has seasons that last for approximately 20 years

The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006

Mars liquid water disappeared billions of years ago

The Great Red Spot storm has lasted for over 300 year

Eris, one of the largest dwarf planets and is further from the Sun than Pluto

The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C

Clara rushes 30m to a truck then turns and walks back. Total travel is 120s what is her average velocity?
navik [9.2K]

Taking into account the definition of velocity, Clara's average velocity is 0.5 m/s.

<h3>Definition of velocity</h3>

Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction. So it is considered a vector magnitude.

In other words, the velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:

velocity= distance traveled÷ time

<h3>Average velocity of Clara</h3>

Clara rushes 30 m to a truck then turns and walks back. Total travel is 120s. Then, you know:

  • distance traveled= 30m rushing + 30m walking back= 60 m
  • time= 120 s

Replacing in the definition of velocity:

velocity= 60 m÷ 120 s

Solving:

<u><em>velocity= 0.5 m/s</em></u>

Finally, Clara's average velocity is 0.5 m/s.

Explain the following observations:
Deffense [45]

Answer and Explanation:

a. An oxygen-filled balloon is not able to float in the air, because the oxygen inside the balloon is of the same density, that is, the same "weight" as the oxygen outside the balloon and present in the atmosphere. The balloon can only float if the gas inside it is less dense than atmospheric oxygen. Helium gas is less dense than atmospheric gas, so if a balloon is filled with helium gas, that balloon will be able to float because of the difference in density.

b. The ship is able to float in the water because its steel construction is hollow and full of air. This makes the average density of this ship less than the density of water, which makes the ship lighter than water and for this reason, this ship is able to float. In addition, the ship is partially immersed, allowing the weight of the ship on the water to counteract the buoyant force that the water promotes on the ship. Weight and buoyant are two opposing forces that keep the ship afloat.
