How can you visit the sun without burning up worksheet answer key

Lesechka [4]

How can you visit the sun without burning up worksheet answer key is a heading for a worksheet that involves mathematical questions to calculate. The attached file displays those mathematical questions.

Before that, the sun is known as a star that is located in the middle of the Solar system. It is a virtually flawless sphere of hot plasma that has been heated by nuclear fusion processes in its center, thereby radiating energy as infrared radiation and ultraviolet light.

It is nearly impossible to visit the sun due to the degree of its temperature and radiation.

From the image attached below which depicts the heading to the question, we have:

a) 5(x - 9) = 2x + 15

Open brackets

5x - 45 = 2x + 15

Collect like terms

5x - 2x = 45 + 15

3x = 60

x = 60/3

x = 20

b) $\mathbf{ 7n - 20 = 9(4n + 1)}$

Open brackets

7n - 20 = 36n + 9

7n - 36n = 20 + 9

- 29 n = 29

n = - 29/29

n = - 1

Therefore, from the given information, we can conclude that It is nearly impossible to visit the sun due to the degree of its temperature and radiation. Also, the value of x = 20 and the value of n = -1

Discuss your reaction to the following statement, companies should not provide training to employees because it is the responsib

serious [3.7K]

Answer:

The statement "companies should not provide training to employees because it is the responsibility of individuals to possess the necessary knowledge and skills prior to becoming employed, is entirely wrong. In just one counter example of how this statement would not persist in work places is public service positions. Consistent demand is needed for public service employees. No college or educational program educates an individual on exact protocol on a specific public service field, further training is always required to provide top quality service. Also another example is in the food industry. Waitresses' or Waiters' responsibilities vary between different restaurants protocols and rules. Training is needed and required for someone to work in that specific restaurant, no one is able to "possess the necessary knowledge and skills prior to becoming employed" due to variety of rules, regulations, and preferences in work places.

A beam of white light goes from air into the water droplet at an incidence angle of 36.2 degrees. what is the angle between the

torisob [31]

A beam of white light goes from air into the water droplet at an incidence angle. The angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.

<h3>What is white light?</h3>

The white light is the ray coming directly from the Sun. When it strikes any glass object, an spectrum of colors with different wavelength is formed.

Given is the angle of incidence, i = 36.2°, the refractive index of water for red light is 1.331 , the refractive index of water for violet light is 1.340 and refractive index of air is 1.

Using the Snell's law, the angle of refraction of red light will be

1.331 x sin r(R) = 1 x sin 36.2

r(R) = 26.342°

Using the Snell's law, the angle of refraction of violet light will be

1.340 x sin r(R) = 1 x sin 36.2

r (V) = 26.152°

Difference in the angle of refraction of red and violet light is

r(R) - r (V) = 26.342 - 26.152 = 0.19°

Thus, the angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.
