The light travels through water and gets reflected off on the glass surface into the water. There had been a 180° phase change between the incident and the reflected wave. This is called Total internal reflection (TIR).
In total internal reflection, in physics, a ray of light in a medium such as water or glass is completely reflected back into the medium from the surrounding surfaces. This phenomenon occurs when the angle of incidence is greater than a certain critical angle called the critical angle.
TIR only occurs when both of the following two conditions are met
Light is in a denser medium and is approaching a less dense medium. The angle of incidence should be greater than the so-called critical angle.Thus, the phases which include the TIR are the incident and the reflected phase and the incident light hits the surface while the reflected light reflects back.

At 2:00 p. M. Two cars start toward each other from towns 240 miles apart. If the rate of one car is 10 mph faster than the other, how fast does each car go if they meet at 5:00 p. M. ? if 3x represents the distance that the slower car traveled, then which expression represents the distance the faster car traveled? 3 x + 10 3 x + 30 3(240).
135 miles represents the distance the faster car traveled.
Just what is distance?Distance is an object's overall movement, regardless of direction. Regardless of an object's starting or ending point, distance can be defined as the amount of ground it has travelled.
If we call the slower vehicle's speed S, the other vehicle's speed is S + 10 mph.
They've been on the road for three hours as of 5:00 p.m. The faster car travels 3(S+10) miles, while the slower one travels 3S miles.
However, the sum of the two distances has to be 240 miles, so 3S+3(S+10)=240,
3S+3S+30=240,
6S=210, and
S=35 mph.
The faster vehicle travels at 45 mph. We can see that 3S is equal to 3x, which means that x=S=35 mph and that the faster vehicle travels 3×45=135 miles.

Mass is used in physics to express inertia, a fundamental characteristic of all matter. Essentially, it is a mass of matter's resistance to changing its direction or speed in response to the application of a force. The change that an applied force produces is smaller the more mass a body has. The kilogram, the unit of mass in the International System of Units, corresponds to 6.62607015 1034 joule seconds using Planck's constant (SI). One joule is produced by multiplying one kilogram by one square meter per second. The kilogram is determined by exact measurements of Planck's constant since the second and the meter have previously been defined in terms of other physical constants.

Stir the liquid occasionally to release the _______________.
Using the concept of thermodynamics, we got heat as an output when we stir the liquid occasionally.
Actually, according to the Clausius statement of the second law of Thermodynamics: Heat can transfer from a hot body to a cold body, but it cannot transfer from a cold body to a hot body unless any external work has been done on the system.
Thus when you stir a hot liquid, due to the phenomenon of the convection (It is a heat transfer process that can occur only in fluids), part of the heat from the hot liquid goes to the medium which you are stirring (Eg. spoon) and another part of heat flows to the surrounding which is at a room temperature. Thus due to these things heat energy is liberated at a higher rate
But when you went on to stir a cold liquid (let’s say it is at 19 °C), you are giving mechanical work on the system. As mentioned in the second law of Thermodynamics the heat gets transferred from cold liquid to the surrounding air (let's say 30 °C ) due to the work given (stir). But the transfer of heat is very small which could make the liquid warm only to a little amount due to which the temperature of the liquid increases (let’s say it is at 25 °C), and convection (heat transfer process in fluids. In here it is from a cold liquid to at air) also occurs a little amount. So to make this hot even more work has to be done on the system (cold liquid) if the system is closed the work to be done can also be reduced.

what is the apparent weight of a 95 KG astronaut on this rocket
Given:
• Acceleration of rocket = 28.0 m/s²
,• Mass of astronaut = 95 kg
Let's find the apparent weight of the astranaut.
In a direct rocket motion, as we are coming towards the Earth the weight reduces while as the rocket is going up, you feel more weighted.
Now, to find the apparent weight of the astranaut, apply the formula:
[tex]A_w=m(g+a)[/tex]Where:
Aw is the apparent weight
m is the mass = 95 kg
g is acceleration due to gravity = 9.8 m/s²
a is the acceleration of the rocket = 28.0 m/s²
Thus, we have:
[tex]\begin{gathered} A_w=95(9.8+28) \\ \\ A_w=95(37.8) \\ \\ A_w=3591\text{ N }\approx3.591\text{ kN} \end{gathered}[/tex]Therefore, the apparent weight of the astranaut is 3.591 kN

what is the horizontal acceleration of an object undergoing projectile motion?
That is acceleration due to the horizontal component of velocity is 0
When the body is on the projectile we tend to take components on the initial velocity for ease of calculation. The velocity is then divided into its components u sinФ and u cosФ where the horizontal component of the velocity of the projectile is shown by u cosФ while the vertical component of the velocity of the projectile is shown by u sinФ
To calculate the acceleration of either component of the velocity is very easy. In this case, we use the third equation of Newton's Equation of motion.
[tex]V^{2}[/tex]-[tex]U^{2}[/tex]=2as
When we calculate the acceleration of the horizontal component of velocity, we find that since the velocity remains the same at both the endpoint and the start no acceleration takes place.
[tex]U^{2}[/tex][tex]Sin^{2}[/tex]Ф-[tex]U^{2}[/tex][tex]Sin^{2}[/tex]Ф=2as
Thus, 2as=0

During an autumn storm, a 0.012-kg hail stone traveling at 20.0 m/s made a0.20-cm-deep dent in the hood of Darnell's new car. What average force didthe car exert to stop the damaging hail stone?
Answer:
1200 N
Explanation:
First, we need to calculate how much time the force was applied. If the stone traveled at 20.0m/s and made a 0.20 cm deep dent, the time is equal to
[tex]\text{ Avg }speed=\frac{distance}{time}\Rightarrow time=\frac{distace}{Avg\text{ }speed}[/tex]Where the distance is 0.20 cm = 0.0020 m and the average speed can be calculated as:
[tex]\text{ avg speed = }\frac{v_i+v_f}{2}=\frac{20\text{ m/s + 0 m/s}}{2}=10\text{ m/s}[/tex]Therefore, the time is equal to
[tex]time=\frac{0.0020\text{ m}}{10\text{ m/s}}=0.0002\text{ s}[/tex]Then, the force can be calculated using the following equation for impulse
[tex]\begin{gathered} Ft=mv \\ F=\frac{mv}{t} \end{gathered}[/tex]Where m is the mass, v is the speed and t is the time, so replacing m = 0.012 kg, v = 20 m/s and t = 0.0001 s, we get
[tex]F=\frac{0.012\text{ kg \lparen20 m/s\rparen}}{0.0002\text{ s}}=1200N[/tex]So, the average force was 1200 N
During autumn, the storm travels at a speed of 20 m/s, then the average force the car has to exert to stop the damaging hail storm is 1200 N.
What is Force?A force in physics is an effect that has the ability to modify an object's motion. A bulk object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can be used to describe force. Being a vector quantity, a force also has magnitude and direction. The SI unit of newton is used to measure it (N). The letter F symbolizes for force.
As per Newton's second law's original formulation, an object's net force is equal to the speed at which momentum is changing over time.
According to the given information in the question,
Speed, s= 20 m/s
Average speed, s = Distance/Time
s = [v(i) + v(f)] / 2
s = (20 + 0)/2
s = 10 m/s
Now calculate the time,
Time, t = 0.0020/10
t = 0.0002 seconds.
Use the equation for impulse,
f × t = mv
⇒f = mv/t
f= (0.012 × 20)/0.0002
f = 1200 N
Therefore, the force applied is 1200 N.

Suppose an experimental arrangement has mass m1= 0.200 kg at the 0.100-m mark and a mass m2= 0.100 kg at the 0.750-m mark. Can the system be put in equilibrium by a 0.050-kg mass? If it can be done, state where it would be placed. If it cannot be done, state why not.
It is to be noted that the system cannot be put in equilibrium by a 0.050kg mass. This is because the point on the stick where it ought to be placed is longer than the actual length of the stick.
What is Equilibrium?In physics, equilibrium is the state of a system where neither its state of momentum nor its internal energy state changes over time. In a meter-stick experiment, the net torque applied to the system must be zero for the system to be in equilibrium.
Assume the center of gravity is at 0.500 m.
Recall that m1 = 0.200kg at 0.100m mark
m2 = 0.100kg at the 0.750m mark
m1(0.500 - 0.100) = m2(0.750 - 0.500) + m3(d-0.500)
0.2(0.4) = 0.1(0.25) + 0.05(d-0.5)
0.055 = 0.05d -0.025
d = 1.6 m
This indicates that the 0.050 kg weight must be placed on the right side, 1.6 m from the center of the scale; however, because the scale is only 0.5 meters long on each side of the center, adding 0.050 to the meterstick is impossible.

a loop of wire is enclosing area 0.04m^2 has a magnetic field passing through its plane at an angle to the plane. the component of the field perpendicular to the plane is 0.12t, and the component parallel to the plane is 0.05t. what is the magnetic flux through this coil?
The magnetic flux through the coil if the component of the field perpendicular to the plane is 0.12t, and the component parallel to the plane is 0.05t is 0.0048 Wb
Φ = B A cos θ
Φ = Magnetic flux
B = Magnetic field
θ = Angle between magnetic field and normal of the surface
A = 0.04 m²
For the component of the field perpendicular to the plane,
B = 0.12 T
θ = 0
Φ = 0.12 * 0.04 * cos 0
Φ = 0.0048 Wb
For the component parallel to the plane,
B = 0.05 T
θ = 90°
Φ = 0.05 * 0.04 * cos 90
Φ = 0
So, to calculate magnetic flux through this coil, the component of the field perpendicular to the plane needs to be used.
Therefore, the magnetic flux through this coil is 0.0048 Wb

a circular loop of radius rotates with angular frequency in the presence of a unifrom magnetic field of magnitude . what is the maximum induced emf? express in terms of the variables (omega), , (pi), , as needed.
The maximum induced emf on the circular loop is = Bπr²ω.
What is electromotive force?When no current is flowing, electromotive force (EMF) equals the terminal potential difference.
Despite the fact that both EMF and terminal potential difference (V) are expressed in volts, they are not the same thing. EMF is the quantity of energy (E) that the battery supplies to each coulomb of charge (Q) that passes through.
Let, the radius of the circular loop is = r.
Angular frequency of rotation is = ω.
And, magnitude of uniform magnetic field = B.
Then, magnetic flux; Φ = B·A = Bπr² cosωt
So, induced emf : ε = dΦ/dt = Bπr²ω sinωt
Hence, the maximum induced emf is = Bπr²ω.
