(2 marks) Explain the meaning of the term frustrated total internal reflection, and describe any advantages or disadvantages arising from this phenomenon. (2 marks)
Answers
The angle of incidence, refractive index, and wavelength are used to determine the critical angle and the angle of refraction at the interface. From there, the distance can be calculated using trigonometry and the decay equation.
To calculate the distance outside the dielectric at which the electric field amplitude drops to 10% of its value at the surface, we need to consider the decay of the electric field in the dielectric material. The angle of incidence (80°) and the refractive index (n = 1.5) are used to determine the critical angle and the angle of refraction at the interface between the dielectric and free space. With these angles, we can calculate the distance at which the electric field amplitude drops to 10% of its value.
Frustrated total internal reflection refers to the phenomenon where total internal reflection does not occur at the interface between two mediums, such as from a higher refractive index medium to a lower refractive index medium. This can happen when the angle of incidence exceeds the critical angle, but instead of all the light being reflected, a small portion of it is transmitted into the second medium. Frustrated total internal reflection can be advantageous in applications like optical fibers and waveguides, where it allows controlled transmission of light. However, it can also be disadvantageous when trying to achieve complete reflection, such as in certain optical devices or when designing systems that rely on total internal reflection for efficient light confinement.

Acceleration is a change in speed or direction over time. In what two ways does the sled accelerate as it descends?
Answers
Answer:
By force and sloppy surface.
Explanation:
By applying force on the sled and slope of the path are the two ways the sled accelerate as it descends. If there is more friction between sled and the ground then force is required to push the sled to move downward while on the other hand, if the path on which sled moves is sloppy then it will move automatically without the use of force, so these two ways can accelerate the sled.

Wanda is taking photos using a lens that sees and records a very narrow view with a focal length longer than 60mm. When her friend asks what type of lens she is using for their photography outing, how does Wanda reply
Answers
Wanda can reply to her friend by saying that she is using a telephoto lens for their photography outing.
A telephoto lens is a type of camera lens that is designed to capture distant subjects by using a longer focal length than a standard lens. Telephoto lenses typically have a focal length of 60mm or longer, which allows them to see and record a very narrow view. This makes them ideal for capturing subjects that are far away, such as wildlife, sports events, and landscapes. Telephoto lenses are also popular for portrait photography because they can create a shallow depth of field, which helps to isolate the subject from the background.

Make a graph of the relationship between the amplitude (x-axis) and decibel level (v-axis) of sound. Describe this relationship.
Answers
The graph of the relationship between amplitude and decibel level of sound is not a linear graph but a logarithmic graph.
It is known as the Sound Intensity Level graph, where the amplitude of the sound is plotted on the x-axis, and the decibel level of sound is plotted on the y-axis.
As the amplitude of the sound increases, the decibel level increases as well. The relationship is not directly proportional, as a small change in amplitude can result in a significant change in decibel level. For example, a sound with an amplitude of 1 Pa has a decibel level of 0 dB, whereas a sound with an amplitude of 10 Pa has a decibel level of 20 dB. This indicates that the decibel level is increasing exponentially with the increase in amplitude.
Moreover, the graph shows that the human ear has a limited range of hearing, which is between 0 dB and 140 dB. Beyond this range, sounds become too loud to hear or can cause damage to the ear. Therefore, it is important to monitor the decibel level of sound to protect our hearing.

Un proyectil es lanzado horizontalmente desde una altura de 12 metro con una velocidad de 80 m/sg. a.Calcular el tiempo de vuelo b. Su alcance horizontal y velocidad de impacto contra el suelo.
Answers
Answer:
t= 1,56 s , x= 124,8 m , v = (80 i^ - 15,288 j ) m/s
Explanation:
Este es un ejercicio de lanzamiento proyectiles, comencemos por encontrar el tiempo que tarda en llegar al piso
y = y₀ + \(v_{oy}\) t – ½ g t²
en este caso la altura inicial es y₀= 12 m y llega a y=0 , como es lanzado horizontalmente la velocidad vertical es cero (v_{oy}=0)
0 = y₀ – ½ g t²
t= √ (2 y₀/g)
calculemos
t= √ ( 2 12 / 9,8)
t= 1,56 s
El alcance del proyectil es la distancia horizontal recorrida
x = v₀ₓ t
x = 80 1,56
x= 124,8 m
La velocidad de impacto cuando toca el suelo
vx = v₀ₓ = 80 ms
\(v_{y}\) = v_{oy} – gt
v_{y} = - 9,8 1,56
v_{y} = - 15,288 m/s
la velocidad es
v = (80 i^ - 15,288 j ) m/s
Traducttion
This is a projectile launching exercise, let's start by finding the time it takes to reach the ground
y = y₀ + v_{oy} t - ½ g t²
in this case the initial height is i = 12 m and it reaches y = 0, as it is thrown horizontally the vertical speed is zero (\(v_{oy}\) = 0)
0 =y₀I - ½ g t²
t = √ (2y₀ / g)
let's calculate
t = √ (2 12 / 9.8)
t = 1.56 s
Projectile range is the horizontal distance traveled
x = v₀ₓ t
x = 80 1.56
x = 124.8 m
Impact speed when it hits the ground
vₓ = v₀ₓ = 80 ms
v_{y} = v_{oy} - gt
v_{y} = - 9.8 1.56
v_{y} = - 15,288 m / s
the speed is
v = (80 i ^ - 15,288 j) m / s

Mitochondria is a type of organelle in the athlete’s cells supplies the energy for cellular function.
Since mitochondria are the cellular organelles in charge of producing aerobic ATP, the "health" of mitochondria is crucial for proper cellular operation
Which organelles that give energy to the cell?Mitochondria. Dictionary Britannica, Inc. Mitochondria, or "powerhouses," are oval-shaped organelles that are present in the majority of eukaryotic cells. During cellular respiration, substances like glucose are converted by mitochondria into ATP, an energy molecule (adenosine triphosphate).
How Mitochondria produce ROS?The generation of ROS by mitochondria can result in oxidative damage to mitochondrial proteins, membranes, and DNA, impairing their capacity to synthesize ATP and perform a wide range of metabolic processes, including the tricarboxylic acid cycle, fatty acid oxidation, the urea cycle, amino acid metabolism, haem synthesis, and FeS center assembly, which are crucial to the normal functioning of most cells. The tendency of mitochondria to release intermembrane space proteins, such as cytochrome c (cyt c), to the cytosol by mitochondrial outer membrane permeabilization (MOMP), and so trigger the cell's apoptotic machinery, can also be increased by mitochondrial oxidative damage. The mitochondrial permeability transition pore (PTP), which opens up the inner membrane to tiny molecules in conditions like ischaemial reperfusion damage, is also induced by mitochondrial ROS generation. So it should come as no surprise that mitochondrial oxidative damage plays a role in a variety of diseases. Additionally, mitochondrial ROS may behave as a modifiable redox signal, impacting a number of activities in the mitochondria, cytosol, and nucleus in a reversible manner.

Answers
The current through the new resistor will be half of the original current.
The resistance of a conductor depends on its material, length, and cross-sectional area, and is given by: R = (ρL) / A
Where R is the resistance, ρ is the resistivity of the material, L is the length, and A is the cross-sectional area.
Since the new resistor has twice the cross-sectional area of the original, its resistance will be half that of the original, assuming the length and material are the same.
According to Ohm's Law, the current through a resistor is directly proportional to the potential difference across it, and inversely proportional to its resistance: I = V / R
where I is the current, V is the potential difference, and R is the resistance.
Since the potential drop across the resistor is the same for the new resistor as for the original, and the new resistor has half the resistance, the current through the new resistor will be twice the current through the original resistor.

would force of gravity be big or small when an object has a seperation distance in 1 meter
Answers
The final gravitational force will be 1/16th of the initial gravitational force. In other words, the gravitational force will decrease when the objects are moved from 1 meter apart to 4 meters apart.
The gravitational force between two objects depends on their masses and the distance between them. According to Newton's law of universal gravitation, the force is inversely proportional to the square of the distance between the objects and directly proportional to the product of their masses.
Let's assume that the masses of the objects remain constant. If the objects are initially placed 1 meter apart and then moved to a distance of 4 meters, we can calculate how the gravitational force changes.
The formula for the gravitational force is:
F = G * (m1 * m2) / r^2
Where:
F is the gravitational force between the objects.
G is the gravitational constant.
m1 and m2 are the masses of the objects.
r is the distance between the objects.
Assuming the masses and the gravitational constant remain constant, we can compare the initial and final gravitational forces.
Let's denote the initial force as F_initial and the final force as F_final. Using the formula above, we can calculate the ratio of the final force to the initial force:
F_final / F_initial = (G * (m1 * m2) / (4^2)) / (G * (m1 * m2) / (1^2))
= (1 / 16) / (1 / 1)
= 1 / 16
This decrease in the gravitational force is a result of the inverse square law. As the distance between the objects increases, the force weakens exponentially. In this case, the force decreases by a factor of 16 because the distance is quadrupled (from 1 meter to 4 meters).

A man is running on the straight road with the uniform velocity of 3m/s. Calculate acceleration.
Answers
Answer:
Answer is zero
Explanation:
Acceleration is defined as the rate of change in velocity. If there’s no change in velocity, then the rate of change is zero, hence the acceleration is zero. The question says the man is running at a uniform velocity (i.e. he’s running at a steady speed in a fixed direction). This means his velocity is constant, or unchanging. Hence, his acceleration is zero.
A man is running on the straight road with the uniform velocity of 3 m/s.
To find out:Acceleration produced by the man.
Solution:Given, the man is running with uniform velocity of 3 m/s.So the velocity did not change.It remains constant.We know, acceleration is the change of velocity per unit time.Since there is no change in velocity in this case, so there will be no acceleration.So, the acceleration produced by the man is zero.Answer:The acceleration produced by the man is zero.
