Explain whether smoke filling up a room is diffusion or not

Physics
1 answer:
pogonyaev3 years ago

Yes, it is diffusion !

Diffusion is the process in which gas, through random movement of particles, tends to fill up the whole volume of the container in which it is placed. So a similar process would lead the smoke, which is in form of gas (or light particles), to fill in the whole room in which it is contained.

Are wind-driven currents found near the surface of the oceans or in the deep waters of the ocean?
drek231 [11]

Wind-driven currents are found NEAR THE SURFACE of the oceans

Explanation:

Surface currents are at the interphase between the hydrosphere and atmosphere. Therefore the feel the greatest effect of drag by wind currents, especially prevailing winds (that blow predominantly in one direction like westerlies and easterlies) within the lower atmosphere.  The deep currents, on the other hand, are more influenced by Coriolis effect of the earth’s rotation. It is these differences in influences of surface and deeper currents that cause Ekman transport in oceans.

Volume of a culinder of length 3.47cm is 1.932cc.find the radius
pashok25 [27]

Answer:

0.421 cm

Explanation:

Volume of a cylinder is:

V = πr²h

where r is the radius and h is the height or length.

Given V = 1.932 cm³ and h = 3.47 cm:

1.932 = πr² (3.47)

0.557 = πr²

r² = 0.177

r = 0.421

The radius is 0.421 cm.

Let f be the function that determines the area of a circle (in square cm) that has a radius of r cm. That is, f ( r ) represents
emmasim [6.3K]

Answer:

f(r)=\pi.r^2\\f(4.3)=58.09\ cm^2

Explanation:

<u>Functions</u>

When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.

The area of a circle is computed by the well-known formula

A=\pi r^2

We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in cm^2.

The required function is

f(r)=\pi r^2

For a radius of 4.3 cm:

f(4.3)=\pi\times  4.3^2=58.09\ cm^2

\boxed{f(4.3)=58.09\ cm^2}
