Answer:

3 Objects that carry instruments into the stratosphere to measure atmospheric conditions

Explanation:

Weather balloons are objects that carries instruments into the stratosphere to measure atmospheric conditions.

They are very important weather measuring device that helps meteorologists in their fore casts.

These balloons are specially designed for high altitudes. They carry very sensitive devices that are very useful in collecting information about temperature, precipitation, pressure e.t.c

A ray of light traveling in water hits a glass surface. The index of refraction of the water is 1.33, and that of the glass is 1

kirza4 [7]

Answer:

$\mu=41.5\textdegree$

Explanation:

From the question we are told that:

Water index of refraction $i_w=1.33$

Glass index of refraction $i_g=1.50$

Generally the equation for Brewster's law is mathematically given by

$\theta=tan^{-1}(\frac{i_g}{i_w})$

$\theta=tan^{-1}(\frac{1.50}{1.33})$

$\theta=48.44 \textdegree$

Therefore Angle of incident to plane \mu (normal at 90 degree to the surface)

$\mu=90\textdegree-\theta$

$\mu=90\textdegree-48.44\textdegree$

$\mu=41.5\textdegree$

A 12. 0 cm object is 9. 0 cm from a convex mirror that has a focal length of -4. 5 cm. What is the distance of the image from th

expeople1 [14]

A mirror equation is an equation that relates object distance and image distance to focal length. The distance of the image from the mirror will be -3 cm.

<h3>What is a mirror equation?</h3>

A mirror equation is an equation that relates object distance and image distance to focal length. It's sometimes referred to as a mirror formula.

$\rm \frac{1}{v} +\frac{1}{u} =\frac{1}{f} \\\\$

The given data in the problem is;

f is the focal length = -4. 5 cm

u is the object distance=12. 0 cm

v is the image distance =?

$\rm \frac{1}{v} +\frac{1}{12.} =\frac{1}{-4.5} \\\\ \rm \frac{1}{v}= \frac{1}{-3} \\\\ \rm v= -3cm$

Hence the distance of the image from the mirror will be -3 cm.
