We know for a fact that D and A can be eliminated from the answer choices because those are both false. we know that both B and C are both very accurate knowing that wave B does have a higher pitch than wave A but also wave A has a louder sound wave than wave B. so i'd say the answer is (C).
Answer:
The total voltage of the circuit is 18 volts.
Explanation:
We have, three identical resistors of resistance 3 ohms are connected in series in a circuit.
For a series combination, the equivalent resistance is given by the sum of individual resistances i.e.
![R_{eq}=R_1+R_2+R_3\\\\R_{eq}=3+3+3\\\\R_{eq}=9\ \Omega](https://tex.z-dn.net/?f=R_%7Beq%7D%3DR_1%2BR_2%2BR_3%5C%5C%5C%5CR_%7Beq%7D%3D3%2B3%2B3%5C%5C%5C%5CR_%7Beq%7D%3D9%5C%20%5COmega)
Let V is the voltage of the battery if the current in the circuit is 2 A. So,
![V=IR](https://tex.z-dn.net/?f=V%3DIR)
![V=2\times 9\\\\V=18\ V](https://tex.z-dn.net/?f=V%3D2%5Ctimes%209%5C%5C%5C%5CV%3D18%5C%20V)
So, the total voltage of the circuit is 18 volts.
The formation of Earth is supported by the statements like, it is a terrestrial planet. it was formed from gas and dust. it was formed in a debris disk from colliding planetesimals.
The given problem is based on the correct statements entitling the description of Earth. Earth is amongst 8 planets in our solar system, that happen to orbit around the sun.
The statements given to describe the Earth are as follows:
- Earth is not an Outer planet. It is an inner planet that lies closest to the sun after Mercury and Venus.
- Earth is a terrestrial planet because it is having a compact and rocky surface. Also, it is known to be an as largest terrestrial planet in the solar system with extensive regions of liquids and water.
- The abundant rocky surfaces have evolved from the cloud of dust and gas, during the post-Big Bang Era. So, it is somewhere true to say that Earth is formed from gas and dust.
- The earlier atmosphere of Earth was known for having proportional layers of Hydrogen and Helium. Hence is quite true to say that the Earth is having an atmosphere of Hydrogen and helium gases, but it is not as thick as the like sun.
- Majority of terrestrial planets are formed from the collision of planetesimals in a debris disk. With Earth being one of them, it is quite correct to consider the given statement.
Thus, we can conclude that the formation of Earth is supported by the statements like: it is a terrestrial planet, it was formed from gas and dust and it was formed in a debris disk from colliding planetesimals.
