"One step in the manufacture of silicon wafers used in the microelectronics industry is the melt crystallization of silicon into a crystalline silicon ingot. This processis carried out within a special furnace. When the newly solidified ingot is removed from the furnace, it is assumed to have a uniform initial temperature of 1600 K, which is below the crystallization temperature. At this temperature, the thermal conductivity of silicon is 22 W/(m•K), the density is 2300 kg/m3, and the heat capacity is 1000 J/(kg•K). The hot solid silicon ingot is allowed to cool in air maintained at a constant ambient temperature of 30°C. The diameter of the silicon rod is 15 cm. End effects are considered negligible. The convective heat transfer coefficient is 147 W/(m2•K). What temperature will exist 1.5 cm from the surface of the ingot after a cooling time of 583 sec (9.72 min)?" Consider the rod as acylinder placed vertically.

A ray at which angle would produce the most glare is at 70 degrees. The answer is letter D. the greater the incident of light is, the greater is its index of refraction and thus having greater angle to produce a light ray.
The ray more the incidence ray, the more will be the reflected ray. As angle of incidence is to angle of reflection.
Glare can be defined as the difficulty in seeing the object due to more brightness. The bright light such as the direct sunlight or the reflected sunlight or the headlight at the nighttime.The more the intensity the more will be glare.
Hence, the ray that will produce most glare is 70 degree.

Energy = （6.626 x 10^-34*3.00 x 10^8)/（4.80 × 10^−7）= 4.14*10^-19 J, which is 3.
Normally, when solving these equations, don't forget to check the units are correct (eg. wavelength is in meters) and dont forget to include the units in the calculation.
Taking into account the definition of photon, energy of a photon, wavelength, frecuency and propagation speed, the correct answer is the option (3): The energy of a photon with aa wavelength of 4.80×10⁻⁷ meter is 4.14×10⁻¹⁹ J.
What is a photon and energy of a photon
You have to know that electromagnetic radiation carries energy, which can be absorbed or emitted. To explain the processes of emission and absorption, Plank and Einstein proposed that the energy of radiation is composed of indivisible units (quanta). In each elemental process only a quantum of light can be emitted or absorbed. Each of these quanta was called a "photon".
The exchanges of energy between matter and radiation take place not continuously, but by discrete and indivisible quantities or quanta of energy. The quantum of energy is proportional to the frequency of radiation.
The relationship between the amount of energy (E) transported by the photon and its frequency (f) is determined by the following expression, where the energy of a photon is obtained by multiplying Planck's constant h by the frequency f of electromagnetic radiation:
E=h×f
What is wavelength, frecuency and propagation speed
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).
On the other side, frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).
Finally, the propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.
The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:
v = f×λ
All electromagnetic waves propagate in a vacuum at a constant speed of 3×10⁸ m/s, the speed of light.
What is the energy of the photon in this case
In this case, you know:
- h= 6.63*10⁻³⁴ Js
- f= v÷λ where v= 3×10⁸ m/s and λ=4.80×10⁻⁷ m
Replacing in the definition of energy of a photon:
E=h× (v÷λ)
E= 6.63×10⁻³⁴ Js× (3×10⁸ m/s ÷4.80×10⁻⁷ m)
Solving:
E= 4.14×10⁻¹⁹ J
Finally, the correct answer is the option (3): The energy of a photon with aa wavelength of 4.80×10⁻⁷ meter is 4.14×10⁻¹⁹ J.

Explanation:
I add a picture of the situation in order to explain the question.
We are going to state the ''zero'' on a horizontal line. Then, we are going to state as positive the sense from left to right.
Now, if the object moves 14 units to the left , we need to subtract to the original position 14 units (because it will be a negative move given that the object is moving to the left) ⇒
It new position will be at .
In general, the first step to solve this kind of exercises is to set a reference system. Then, it is very important to draw the situation.
