Answer:
the index of refraction for the transparent material is 1.48
Explanation:
let n1 = 1.0 be the refractive index of air and n2 be the refractive index of the trasnparent material.
then:
Snell's Law state that:
n1×sin(∅1) = n2×sin(∅2)
where ∅1 = 56.0° is the angle of incidence and ∅2 = 90 - 56.0 = 34° be the angle refraction.
n1×sin(∅1) = n2×sin(∅2)
n2 = n1×sin(∅1)/sin(∅2)
= (1.0)×sin(56.0°)/sin(34.0°)
= 1.48
Therefore, the index of refraction for the transparent material is 1.48
Answer:
(a) How much heat transfer is required to raise the temperature of a 0.750-kg aluminum pot containing 2.50 kg of water from 30.0 °C to the boiling point and then boil away 0.750 kg of water?
(b) How long does this take if the rate of heat transfer is 500 W? 1 watt = 1 joule / second (1W = 1 J/s).
(a) The total heat required is 2.47 × 10 ⁶ J
(b) It takes 82.3 min

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection<span> is equal to the </span>angle of incidence.<span> Both </span>angles<span> are measured with respect to the normal to the mirror.</span>
