Answer:
They all burn fossil fuel is the correct answer.
Explanation:
Cars, power plants, and furnaces all burn fossil fuels such as coal, natural gas, heavy oils, petroleum, oil.
Burning of these fossil fuels results in a release of a huge amount of carbon dioxide and sulfur dioxide gas, into the surrounding that causes air pollution, global warming, acid rain, and these gases present in the environment are highly corrosives and makes suffocating in the environment.
Answer:
6402.86 N
Explanation:
taking into account the energy-work theorem, we can write the following equation
![\begin{gathered} W=K_f-K_i \\ Fd=\frac{1}{2}mv_f^2-\frac{1}{2}mv_i^2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20W%3DK_f-K_i%20%5C%5C%20Fd%3D%5Cfrac%7B1%7D%7B2%7Dmv_f%5E2-%5Cfrac%7B1%7D%7B2%7Dmv_i%5E2%20%5Cend%7Bgathered%7D)
Where F is the force, d is the distance, m is the mass, vf is the final velocity and vi is the initial velocity.
Solving for F, we get:
![F=\frac{mv_f^2-mv_i^2}{2d}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bmv_f%5E2-mv_i%5E2%7D%7B2d%7D)
Replacing m = 830 kg, vf = 0 m/s, vi = 1.8 m/s, and d = 0.210 m, we get:
![F=\frac{(830)(0)^2-(830)(1.8)^2}{2(0.210)}=-6402.86\text{ N}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B%28830%29%280%29%5E2-%28830%29%281.8%29%5E2%7D%7B2%280.210%29%7D%3D-6402.86%5Ctext%7B%20N%7D)
Therefore, the magnitude of the force is 6402.86 N
Answer:
Argon
Explanation:
Argon, an inert gas, is the third most abundant gas in the atmosphere.
Answer:
The correct answer to the following question will be "B is younger than D".
Explanation:
- In geology as well as important aspects, that stratum seems to be a coating of sedimentary rock, and perhaps igneous rock produced mostly on the planet's surface, including locally compatible features that make anything from other levels or layers.
- Hardness or structure including its rock to classify the surfaces from which they formed. Usually, the larger and denser the molecules are, the older that rock as well as the deeper its surface it originated from. Toughness could be evaluated using a straightforward fingernail as well as a pocket platform.
So that the above is the right answer.
