Explain the term the refractive index of glass is 1.5​

Answers

Answer:

Refractive index of a glass is 1.5 means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.

Explanation:

Refractive index is defined as a ratio between the speed of light in a vacuum and the speed of light in a medium. Since the refractive index is a ratio between two speeds it is a dimensionless number. For the glass, having a refractive index of 1.5, means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.

Vi = 30m/s

Then acceleration = 75-30/5

Explanation:

Answers to the rest:

1. B) macroscopic outputs.

2.A) a microscopic change creating a macroscopic output

3.B) Because the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.

4.A) Heat is applied to a solid, causing its molecules to move quickly.

5.A) strontium, sodium, copper, potassium

When fireworks explode, sound and light are produced, these are examples of macroscopic outputs.

The macroscopic scale is a scale where objects are large enough to be visible using the eyes or any other sense.

Fireworks produce sufficient sound and light to be observed without the need for any specific device.

Conversely, microscopic scale refers to the scale in which we cannot be observed by using the eye and we need specific tools to observe these phenomena (e.g., a microscope).

In conclusion, when fireworks explode, sound and light are produced, these are examples of macroscopic outputs.

The apparent height of a building 10.5 km away is 0.02 radians. What is the approximate height of the building to the nearest meter

Answers

Answer:

Approximate height of the building is 23213 meters.

Explanation:

Let the height of the building be represented by h.

0.02 radians = 0.02 × [tex]\frac{180^{o} }{\pi }[/tex]

                     = 0.02 x (180/[tex]\frac{22}{7}[/tex])

0.02 radians  = 1.146°

10.5 km = 10500 m

Applying the trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

So that,

Tan 1.146° = [tex]\frac{h}{10500}[/tex]

⇒ h = Tan 1.146° x 10500

      = 2.21074 x 10500

      = 23212.77

h = 23213 m

The approximate height of the building is 23213 m.

A 400-kg space probe has a weight of 3,560 N on one of the above planets. According to the table
above, on which planet is the space probe? Show your work.

Answers

Answer:

Venus

Explanation:

To know the correct answer to the question, we shall determine the weight of the space probe on each planet to see which will correspond to 3560 N.

This is illustrated below:

For Mercury:

Mass = 400 Kg

Gravitational force = 3.7 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 3.7

Weight = 1480 N

For Venus:

Mass = 400 Kg

Gravitational force = 8.9 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 8.9

Weight = 3560 N

For Earth:

Mass = 400 Kg

Gravitational force = 9.8 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 9.8

Weight = 3920 N

For Neptune:

Mass = 400 Kg

Gravitational force = 11 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 11

Weight = 4400 N

For Jupiter:

Mass = 400 Kg

Gravitational force = 23.1 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 23.1

Weight = 9240 N

SUMMARY:

Planet >>>>>> Weight

Mercury >>>> 1480 N

Venus >>>>>> 3560 N

Earth >>>>>>> 3920 N

Neptune >>>> 4400 N

Jupiter >>>>>> 9240 N

From the above calculations, we can see that the weight of the space probe (i.e 3560 N) correspond to the weight on venus (i.e 3560 N)
