Answer:
Option C
Explanation:
Revolution: When an object moves around another object it is called revolution.
Rotation: When an object spins around its axis it's called rotation
Answer:
173.45 K
Explanation:
This an Adiabatic process because no energy is lost by thermal conduction on expansion. We will be using this Adiabatic condition and ideal gas equation to solve the question.
From idea gas equation;
PV = nRT
-----(1)
where
P is pressure of the gas
V is volume of the gas
n is number of moles
R is gas constant 8.31441 J K-1 mol-1.
T is temperature in Kelvin
For Adiabatic Condition;
----(2)
Substituting equation(1) into equation(2)
Eliminating the constants and simplify with exponent
Making T₂ the subject of the formula;
The temperature when the initial volume has quadrupled ⇒ V₂ = 4V₁
⇒
Since air is diatomic, we assume k = 1.4
∴
T₂ = 173.45 K
Answer:
Explanation:
the shape of the continents are all different, but they look like they match if you put them together. The theory of continental drift is most likely true because the continents do look like they have had a connection.
That there are not significate amounts of dark matter wihtin our solar system.
- The dark matter is a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity.
- The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface is known as gravitational attraction.
- The luminous normal matter, such as protons, neutrons, electrons, and atoms in the universe, there are about 4 grams of nonluminous normal matter, mainly intergalactic hydrogen and helium.
