Einstein showed how the photoelectric effect could be understood
by treating light as a stream of particles, with each particle's energy
depending on the color of the light.
Einstein is famous for his work in Relativity. But it was his explanation
of the photoelectric effect... now a pretty obscure topic ... that won him
his only Nobel Prize.
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
The steel would expand by 4. 8 * 10^-3 cm
<h3>How to determine the linear expansion</h3>
The change in length ΔL is proportional to length L. It is dependent on the temperature, substance, and length.
Using the formula:
ΔL= α LΔT
where ΔL is the change in length L = 10cm
ΔT is the change in temperature = 60° - 20° = 40° C
α is the coefficient of linear expansion = 1.2 x 10^-5 °C
Substitute into the formula
ΔL =
ΔL = cm
Therefore, the steel would expand by 4. 8 * 10^-3 cm
