Answer:

1.3636

Explanation:

Write the expression for the refractive index.

n=c/v

c= speed of light in air

v= speed of light in material

=(3×10^8 m/s)/(2.2×10^8 m/s)

 =1.3636

Answer:

The material is silica quartz.

Explanation:

Given that,

Speed of light in material v=2.07\times10^{8}\ m/s

Speed of light  in vacuum c=3.00\times10^{8}\ m/s

We need to calculate the refractive index

Using formula of refractive index

n=\dfrac{c}{v}

Where, c = Speed of light  in vacuum

v=Speed of light  in material

Put the value into the formula

n=\dfrac{3.00\times10^{8}}{2.07\times10^{8}}

n=1.44

We know that,

Refractive index of silica quartz  is between 1.40 to 1.55

So, This is the refractive index of silica quartz.

Hence, The material is silica quartz.

1.) What statement best explains the type of population growth seen in Belize according to the 2010 age structure diagram?
Art [367]

Answer:

1. Belize has a high birth rate and a low death rate.

2. Belize will have a rapidly growing population over the next twenty years.

Explanation:

Belize has a high birth rate and a low death rate. Belize is in the phase II of the demographic transition model. Their population is growing exponentially. This is due to lowering death rates while the birth rates are still high.

Belize will have a rapidly growing population over the next twenty years. When the age structure diagram has a wider base than the middle or top age groups, this indicates a population that is rapidly growing. Belize is early in the transition model and still has high birth rates. Countries like Belize typically have lower opportunities for education for women of reproductive age, can have high infant mortality, and can have high emigration rates.

Is the star moving toward earth, away from earth, or is there not enough information provided to determine its motion?
ivanzaharov [21]

If a star is moving towards Earth, shift towards the blue end of the spectrum, this is called blue shift. If the star is moving away from Earth the light from that star will be red and is called red shift .

The faster a star moves towards the earth, the more its light is shifted to higher frequencies. In contrast, if a star is moving away from the earth, its light is shifted to lower frequencies on the color spectrum

if a star is moving towards Earth, it appears to emit light that is shorter in wavelength compared to a source of light that isn't moving. Because shorter wavelengths correspond to a shift towards the blue end of the spectrum, this is called blue shift.

If the star is moving away from Earth, its light will lose energy to reach Earth, therefore the light from that star will be red and is called red shift
