Answer:

medium 1 = air

medium 2 = Lucite

Explanation:

Part a)

here the refractive index of first medium is 1.0003

so from the given table this is the refractive index of air

so medium 1 is AIR

Part b)

As per law of refraction we know that

n_1sin\theta_1 = n_2 sin\theta_2

here we know that

n_1 = 1.0003

\theta_1 = 72.5

\theta_2 = 39.6

now from Snell's law we will have

1.0003 sin(72.5) = n_2 sin39.6

so we have

n_2 = \frac{1.0003(sin72.5)}{sin39.6}

so we have

n_2 = 1.50

so medium 2 is LUCITE

A thin uniform cylindrical turntable of radius 2.2 m and mass 35 kg rotates in a horizontal plane with an initial angular speed
fenix001 [56]

Explanation:

The given data is as follows.

    M = 35 kg,    radius (r) = 2.2 m,

     m = 17 kg,     = 11 rad/s

We assume that will be the final angular speed.

Now, according to the conservation of angular momentum.

         L_{1} = L_{2}

or,    I_{1} \times \omega_{1} = I_{2} \times \omega_{2}

Putting the given values into the above formula as follows.

  I_{1} \times \omega_{1} = I_{2} \times \omega_{2}

   

or,  

      = \frac{(0.5 \times 35 \times (2.2)^{2}) \times 11}{(0.5 \times 35 \times (2.2)^{2} + 17 \times (1.5)^{2})}

      = 7.58 rad/s

Thus, we can conclude that the angular speed of the clay and turntable is 7.58 rad/s.
