Answer:

three times

Explanation:

Heat added is calculated according to the following equation

Q = mcΔT

where Q is the heat added

           c is the specific heat capacity (of lead for the purposes of this question)

           ΔT is the temperature change in Kelvin or degree Celsius

Q1 for heating lead = mc(373K-298K) = 75mc

Q2 for heating copper = m(3c)(373-298) = 225mc = 3(75mc) = 3Q1

Answer:

n = 1,875

Explanation:

The speed of light in vacuum is constant (c) and in a material medium it is

          v = d / t

The refractive index of a material is defined by

         n = c / v

         

Let's look for the speed of light in the material, in general the length that light travels is known, this value is high, x = 1, when we place a block on the road, a small amount is lengthened by the length of the block, which in general is despised

These measurements are made on a digital oscilloscope that allows to stop the signals and measure their differences, that is, the zero is taken when the first ray arrives and the time for the second ray is measured,

         

         v = d / t

         v = 1 / 6.25 10⁻⁹

         v = 1.6 10⁸ m / s

we calculate the refractive index

        n = 3 10⁸ / 1.6 10⁸

        n = 1,875
