A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.550 and

devlian [24]

To solve this exercise it is necessary to apply the concepts related to the Snells law.

The law defines that,

$n_1 sin\theta_1 = n_2 sin\theta_2$

$n_1 =$ Incident index

$n_2 =$ Refracted index

$\theta_1$ = Incident angle

$\theta_2 =$ Refracted angle

Our values are given by

$n_1 = 1.550$

$n_2 = 1.361$

$\theta_2 =90\° \rightarrow$ Refractory angle generated when light passes through the fiber.

Replacing we have,

$(1.55)sin \theta_1 = (1.361) sin90$

$sin \theta_1 = \frac{(1.361) sin90}{(1.55)}$

$\theta_1 =sin^{-1} \frac{(1.361) sin90}{(1.55)}$

$\theta_1 =61.4\°$

Now for the calculation of the maximum angle we will subtract the minimum value previously found at the angle of 90 degrees which is the maximum. Then,

$\theta_{max} = 90-\theta \\\theta_{max} =90-61.4\\\theta_{max}=28.6\°$

Therefore the critical angle for the light ray to remain insider the fiber is 28.6°

The 500 series bullet train travels between Tokyo and Hakata, Japan. If it is heading north with a momentum of 13,194,098.64 kg

Hitman42 [59]

Answer:

The mass of the 500 series bullet train is 181.4 tonnes.

Explanation:

The momentum is given by:

$p = mv$

Where:

m: is the mass =?

v: is the velocity = 261.8 km/h

p: is the momentum = 13194098.64 kg*m/s

By solving the above equation for "m" we have:

$m = \frac{p}{v} = \frac{13,194,098.64 kg*m/s}{261.8 km/h*\frac{1000 m}{1 km}*\frac{1 h}{3600 s}} = 181.4 tonnes$

Therefore, the mass of the 500 series bullet train is 181.4 tonnes.

I hope it helps you!
