Answer:
Protraction and retraction are opposite of each other.
Explanation: For example, here are difference between the two.
1. Protraction occurs when the lower has is pushed forward to stick to the chin, Retraction, being the opposite pulls the lower jaw backward.
2. Scapular retraction, this help to move the shoulder blade(scapula) towards the spine, also Protraction being the opposite help to move the shoulder blade away from the spine.
In the task you are supposed to explain the process of Dry ice, which is solid changing into CO2 (Carbon dioxide) which is gas.
Dry ice is frozen CO2. Turning dry ice into CO2 is a process called sublimation.
Helllo fellow brainly student!
The best answer is A- with a screen.
This is the best choice because
what this means is to use a sifter.
A sifter is a screen like tool you can
Use to make the lumps disappear from
Flour, sugar, and other cooking ingredients.
Hope this helps! Have a jolly evening.
This question is incomplete, the complete question is;
The Figure shows a container that is sealed at the top by a moveable piston, Inside the container is an ideal gas at 1.00 atm. 20.0°C and 1.00 L.
"What will the pressure inside the container become if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant?"
Answer:
the pressure inside the container become 0.625 atm if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant
Explanation:
Given that;
P₁ = 1.00 atm
P₂ = ?
V₁ = 1 L
V₂ = 1.60 L
the temperature of the gas is kept constant
we know that;
P₁V₁ = P₂V₂
so we substitute
1 × 1 = P₂ × 1.60
P₂ = 1 / 1.60
P₂ = 0.625 atm
Therefore the pressure inside the container become 0.625 atm if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant
Answer:
Air masses tend to move from west to east.
