A0.5-cm diameter air bubble at 5°c and 3 atm pressure rises to the surface. determine its final diame- ter when t 25°c and p 1 atm. (ignore any water vapor in the bubble.)

d=0.738cm

Explanation:

We divide this problem in two parts, below the surface is part 1 (where we have ), and on the surface part 2 (where we have ).  In this case, pressure, volume and temperature will vary, and n will remain constant because the amount of air is always the same (and R is always a constant), so we have .

We can then do:

The volume of a sphere is , so we can write

Which is

And obtain our radius for the bubble on the surface:

Since the diameter is 2 times the radius this can be written as (the factor 2 cancels out):

And we put our values in S.I.:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
