As you descend, the pressure of the air increases and the volume of the air decreases as it becomes squeezed by the pressure.
The ratio is 1/pressure.
At 20 meters below the surface, the pressure of the air is 3 atm.
Time that oxygen tank can last = 1/3 x 60 = 20 minutes <span />
A rigid body is one for which all the parts maintain the same positions relative to one another. I cannot deform or change shape in any way. It can only translate and rotate. It is an idealization. There is no such thing as a perfectly rigid body.
A deformable body is one that can distort. It would normally refer to a solid object so that as it deforms, it sort of deforms in a way that it could return to its starting shape if all the external forces were removed that caused it to deform. I don’t think of a blob liquid as being a deformable body even though a liquid can clearly deform. An object made of rubber is the idea that I have in mind for a deformable body.
Answer: The corridor is 82.825 meters long
Explanation:
Hi, to answer this question we have to apply the next formula:
d = (t×c)/2
Where:
Speed of sound c = 331.3 m/s at 0°C
t = time = 0.5 s.
d = distance
Replacing with the values given:
d = (Δt×c)/2 = 0.5×331.3/2 = 82.825 m
The corridor is 82.825 meters long
Feel free to ask for more if needed or if you did not understand something.
Answer:movemet
Explanation:Rolling friction is the resistive force that slows the wheels motion on other solid surface while static sliding occurs when the thickness of the fluid is great, they is no movement
