Answer:
It might be 2 and 3 but tell me if I'm wrong cause I'm not 100% sure
When they were full of air, then the Pressure was the Highest 'cause of the larger force under the specified area as compared to when we released it.
We decreased the area of our cheek, so pressure increased and air flows from the cheek (area of high pressure) to the atmosphere (Area of the Lower pressure).
Air flows from Cheek to the Outside of your mouth i.e., in open air.
Hope this helps!
Alcohal is in liquid state and in plasma free electrons are present
Answer:
The answer to your question is: number 2 is correct.
Explanation:
Formula
F = m x a
![a = \frac{F}{m}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7BF%7D%7Bm%7D)
The formula shows that acceleration and mass and inversely proportional, then if the mass increases 3 times, then the acceleration must diminishes 3 times.
1. The object will accelerate the same amount as before because the mass does not affect the object’s acceleration.
This option is incorrect, the acceleration must diminish.
2. The object will accelerate 1/3 as much because if you apply the same net force but increase the mass, the acceleration will decrease. This option is correct, is what i describe above.
3. The object will not accelerate because now it is too heavy.
this option is wrong, because the object will accelerate.
4. The object will accelerate 3 times as much because if you apply the same net force and increase the mass, the acceleration will increase. This option s incorrect, the acceleration will diminish not increase.
Answer:
Explanation:
It is a physical change .
If we start from 10 atm of pressure and - 40 celsius of temperature to 20 atm of pressure and 70 celsius of temperature , it is a change in which pressure increases and temperature also increases that means heat is added up to the gas . If we cool the gas we can retrieve its earlier pressure and temperature .
So it is a physical change . In physical change , we can retrieve the old position by simple means.
