What are the main problems associated with using maps?

1 answer:

8 0

The main problems with using maps are that:
- It could be upside down (yes, it happens in real life and not just movies!)
- The scale could be inaccurate and thus you either misjudge your distance or miss your turn.
- The actual map itself can be a bit confusing to read.

Using Wien’s Law, estimate the wavelength at which these common materials radiate their peak brightness (show your work):

SSSSS [86.1K]

Explanation:

Wien’s Law:

$\lambda _{max}\propto \frac{1}{temperature}$

The law states that the wavelength at which black body emits maximum heat is inversely proportional to the temperature of the body in Kelvins.

$\lambda _{max}=\frac{2.9\times 10^{-3}}{T}$

1) Walls at 300 K

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{300 K}$

$\lambda _{max}=9.666\times 10^{-6} m$

2) Ice water at 273 K :

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{273 K}$

$\lambda _{max}=1.062\times 10^{-5} m$

3) Hot water at 373 K :

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{373 K}$

$\lambda _{max}=7.775\times 10^{-6} m$

4)Skin at 310 K:

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{310 K}$

$\lambda _{max}=9.355\times 10^{-6} m$

5)An incandescent light bulb at 3000 K

$\lambda _{max}=\frac{2.9\times 10^{-3} mK}{3000 K}$

$\lambda _{max}=9.666\times 10^{-7} m$

Watch the Submarine Slide portion of the Slides topic of the animation. How can a submarine slide at the edge of a continental s

Morgarella [4.7K]

Answer:

A. by pushing water being pushed into a bulge ahead of the advancing underwater debris flow.

Explanation:

The submarine landslides are a type of landslides that transport the sediments downward and thus the ocean floor is filled with the deep deposits of the sediments due to the downwards driving stress. And theses takes place in a variety of different ways including the planets as low as 1 degree.

They tend to be caused by various geologic attributes and these include the weak geologic layers, an example of Norway.

Overpressuring of the rocks strata, due to the deposition that occurs in the river. Some earthquakes and the associated environmental stresses, groundwater seewa[page and the glacial loadings.

Various hazards are associated with the submarine landslide like that of the Tsunamis ad an example of this landslides tsunamis are the landslides if the Papua new guinea as the slides depends on nature and the waves velocity and the wavelength.

Helppppp please I have this homework due tomorrow!!

If you could dig a tunnel right through the Earth you could theoretically free-fall to the centre of our planet in just eighteen minutes. You can’t, of course: such a tunnel would have to tolerate temperatures as high as the surface of the Sun and pressures three and a half million times greater than those at the Earth’s surface.

What layer of the atmosphere is extremely cold,

N76 [4]

Answer:

Mesosphere

Explanation:

The mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 C).
