vfiekz [6]3 years ago
6 0

Answer:

Dispersion

Explanation:

<u>Dispersion is the phenomenon of the splitting of the light into its constituent colors when it passes through the prism.</u> White light is composed of seven colors which are Violet, Indigo, Blue, Green, Yellow, Orange, Red, written in the form of increasing wavelength. When the light passes through the prism it splits into these seven colors.

What are the similarities &amp; differences between a thermistor and a light dependent resistor in physics?
viva [34]

An LDR's resistance changes with light intensity, while a thermistor's resistancce changes with temperature.

In dark, LDR's resistance is large and in the day/light LDR's resistance is small.

At low temperature, thermistor's resistance is large, while at large temperature it resistance is small.

In an LDR Resistance increases as light intensity falls, while in a thermistor resistance falls as temperature falls.

Geothermal energy is derived from the sun. True or False?
pashok25 [27]
<span>So we want to know is it true or false that geothermal energy is derived from the Sun. Geothermal energy is heat energy that is stored in the Earth. Solar energy is energy that we get by collecting sunlight via solar collectors and turning it into electrical energy. So the answer is FALSE. </span>

star a and star b have measured stellar parallax of 0.58 arc second and 0.73 arc second, respectively. which star is closer?
goldenfox [79]

Star B is closer than star A, because 1/ 0.58 = 1.72 pc, while 1/.73 = 1.36 pc.

<h3>What is stellar parallax and distance measurement using stellar parallax?</h3>

To calculate the distances to nearby stars, astronomers employ a phenomenon known as parallax. The apparent displacement of an object due to a change in the viewer's point of view is known as parallax. The distances between close stars can be calculated using this phenomenon. A nearer star will seem to move against the farther-off background stars as the Earth revolves around the Sun. By measuring a star's position once, then again six months later, astronomers can establish the apparent shift in location of that star. The apparent motion of the star is referred to as stellar parallax.

A straightforward correlation exists between the distance of a star and parallax angle:

d=\frac{1}{p}

The distance d and parallax angle p are both measured in parsecs and arcseconds, respectively.

Stellar parallax of star A= 0.58 arcseconds

Stellar parallax of star B= 0.73 arcseconds

So, on applying the formula,

The distance of the star A= 1.72pc

And the distance of the star B= 1.36pc

Therefore, star B is closer than star A.

How close is the nearest star in miles?
Tamiku [17]
No one knows yet, but Alpha Centauri is an obvious target. It's the nearest star system to our sun at 4.3 light-years away. That's about 25 trillion miles (40 trillion km) away from Eart
