polet [3.4K]3 years ago
3 0

Answer:

85.654988MHz

Explanation:

 f = C/λ

λ (Lambda) = Wavelength in meters

c = Speed of Light (299,792,458 m/s)

f = Frequency (MHz)

299,792,458 m/s. ÷ 3.5. = 85.654988MHz

Which of the following statements is true about the variation of pressure in function of the depth? O Pressure decreases exponen
mrs_skeptik [129]

Answer:

The answer is: Pressure increases linearly with the depth

Explanation:

In this case, the definition of pressure is:

P = \frac{F}{A}

where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider \rho = m/V, then

P = \frac{mg}{A} = \frac{\rho Vg}{A}.

Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.

So

P = \frac{A\rho gh}{A}= \rho g h,

which means that pressure increases linearly with the depth in a factor of \rho g.

Does the elf owl's small size allow it to live in cacti
kaheart [24]
Habitat
-In the Sonoran Desert region, elf owls are found mainly in riparian habitats (places where there is water), or in areas where saguaro cactus are plentiful.

Range
-Elf Owls are found from the southwest USA to Central Mexico and Baja California. Northern populations winter in Central Mexico and on the Pacific slope north to Sinaloa, Mexico.

Wild Status
-The most important threat to the elf owl is habitat loss both of its riparian forest habitat and desert-scrub habitats. In Arizona, the elf owl is not uncommon, but it's numbers are decreasing in California and Texas.

-So I mean like ya it's possible that they could live in cacti. Sorry that I couldn't give you a straight answer.
