Answer:
Option C is the correct answer.
Explanation:
Absolute pressure is sum of gauge pressure and atmospheric pressure.
That is
![P_{abs}=P_{gauge}+P_{atm}](https://tex.z-dn.net/?f=P_%7Babs%7D%3DP_%7Bgauge%7D%2BP_%7Batm%7D)
We have
![P_{abs}=550.280 kPa\\\\P_{atm}=1atm=101325Pa=101.325kPa](https://tex.z-dn.net/?f=P_%7Babs%7D%3D550.280%20kPa%5C%5C%5C%5CP_%7Batm%7D%3D1atm%3D101325Pa%3D101.325kPa)
Substituting
![P_{abs}=P_{gauge}+P_{atm}\\\\550.280=P_{gauge}+101.325\\\\P_{gauge}=448.955kPa](https://tex.z-dn.net/?f=P_%7Babs%7D%3DP_%7Bgauge%7D%2BP_%7Batm%7D%5C%5C%5C%5C550.280%3DP_%7Bgauge%7D%2B101.325%5C%5C%5C%5CP_%7Bgauge%7D%3D448.955kPa)
Option C is the correct answer.
The answer to this question is a) sulfur
Hold on and let's discuss this realistically.
Because of gravity, there are two forces between the Earth and me. One draws me toward the Earth. The strength of that force is what I call my "weight". The other force draws the Earth toward me, and has the same strength.
The strength of these forces depends on the masses of the Earth and me. If the strength just tripled, that means that at least one of us just picked up a lot more mass. If the Earth suddenly became three times as massive, then the weight of everything and everybody on it would suddenly triple, and I'm pretty sure it would be the end of all of us before too long.
If it was only MY mass that suddenly tripled, that would mean that I had gone tearing through my house and the neighbour's house, eating everything in sight including the 2 couches, 3 dogs, and 6 TVs. Naturally, just as you would expect, my weight changed from 207 to 621, and my skin is stretched really tight.
ooohhh
Solution:
Make an Observation - An indoor plant in a dark room withers faster than the same plant in a room with ample sunlight.
Ask a question- Why do certain indoor plants die faster based on where they are placed in the house?
State a hypothesis- Sunlight is probably essential for plants to grow and live.
Run an experiment- Get two potted plants. Cover one with black paper. Place both plants outside in sunlight. See what happens to each plant after one week.
Analyze the results-The plant in the pot with black paper withered. The other plant was healthy.
Communicate the results to others - Plants need sunlight to make food so they can live.
