3. If a certain quantity of gas has a volume of 30 cm3 at a pressure of 1 × 105 Pa, what is its volume when the pressure is
arlik [135]

We know that:

                             P_{1}V_{1}= P_{2}V_{2}               .......(1)

Given at P_{1}=30cm^3 , V_{1}=10^5Pa

a)

When P_{2}=2*10^5Pa , V_2=?

Using equation (1)

                                    30*10^5=2*10^5*V_2

                                     V_2=30/2=15cm^3

b)

When P_2=5*10^5Pa, V_2=?

using equation (1)

                                     30*10^5=5*10^5*V_2

                                    V_2=30/5=6cm^3

A submarine periscope uses two totally reflecting 45-45-90 prisms with total internal reflection on the sides adjacent to the 45
Likurg_2 [28]

Answer

Given,

Periscope uses 45-45-90 prisms with total internal reflection adjacent to 45°.

refractive index of water, n_a = 1.33

refractive index of glass, n_g = 1.52

When the light enters the water, water will act as a lens and when we see the object from the periscope the object shown is farther than the usual distance.
