When a shaft of light approaches a smooth polished face and the light shaft bounces back, it's called the reflection of light. The incident light shaft which lands upon the face is said to be reflected off the face. The shaft that bounces back is called the reflected shaft.

When light is reflected on a aeroplane face the angle of reflection is equal to the angle of prevalence i.e. θr = θi.

Angle of prevalence is the angle between the incident shaft and the reflecting face.

Angle of reflection

This is the angle between the reflected shaft and the normal shaft on a reflecting face.

Angle of reflection is analogous to angle of prevalence.

Thus, the reflection of light is the shaft that hits the face and reflects back to the atmosphere.

going based off of the calandar, you just start from the 4 at the bottom and then just count up as you go through it agains starting back at the top.

Answer: the 19th

Explanation:

count the number of days it takes you to get from full moon (20th) to no moon (4th)

it takes 15 days to get to the no moon phase

so theoretically if we add 15 days to the 4th when there was no moon, we should find the day when there is a full moon

4 + 15 = 19

so the full moon should happen on the 19th :))

Answer:

30km

Explanation:

Distance= speed x time

15x2=30km

The average reaction distance is around 1 second at 20 mph. Let's say that the distance covered by the vehicle in 1 second is 8 meters. Therefore, the reaction distance is 8 meters.

Braking distance is the distance the vehicle travels from the time the driver applies the brakes until the time the vehicle comes to a complete stop. This distance is affected by many factors such as road conditions, tire conditions, and the condition of the brakes. On dry roads, the average braking distance is around 4 times the speed of the vehicle in meters.

Let's say the vehicle weighs 1,000 kg and has good brakes and tires. In this case, the braking distance would be around 24 meters (4 x 20 x 0.25).

Therefore,Stopping Distance = Perception Distance + Reaction Distance + Braking Distance= 7.5 + 8 + 24= 39.5 meters.

Now, let's calculate the distance required to stop a vehicle traveling at a speed of 40 mph.

Stopping Distance = Perception Distance + Reaction Distance + Braking Distance.

As the length of the vehicle and the reaction time of the driver do not change, the only variable that changes in this equation is the braking distance.

Therefore, Stopping Distance = Perception Distance + Reaction Distance + Braking Distance= 7.5 + 8 + (4 x 40 x 0.25)= 79 meters.

Therefore, if the speed of a vehicle doubles from 20 mph to 40 mph, the distance required to stop the vehicle increases by 4 times.

Explanation:

The projectiles launch allows to find the answer for the initial velocity of the stone is:

            v = 17.71 m / s

Projectile launching is an application of kinematics for motion in two dimensions, where there is no acceleration on the x axis and the acceleration on the y axis is the gravity acceleration.

In the attached diagram we can see a corner of the movement. Where the x axis is horizontal and the y axis is vertical, where the zero of the system is at the base of the cliff

In this case the stone is thrown horizontally, therefore its initial vertical speed is zero, let's find the time it takes to reach the base of the cliff

           y = y₀ + \(v_{oy}\) t - ½ g t²

where y and y₀ are the current and initial position, \(v_{oy}\) is the initial vertical velocity, g the acceleration of gravity and t the time

When reaching the bottom its height is zero (y = 0) and the highest part its initial height is y₀ = 25.00 m

           0 =y₀ + 0 - ½ g t²

          t = \(\sqrt{\frac{2y_o}{g} }\)

Let'se calculate

           \(t = \sqrt{ \frac{2 \ 2.25 }{9.8 } }\)

           t = 2,259 s

They indicate that the stone fell at a horizontal distance of 40 m,

           x = \(v_{ox}\) t

            v_{ox} = \(\frac{x}{t}\)

           v_{ox}  = \(\frac{40}{2.259}\)

           v_{ox} = 17.71 m / s

In conclusion, using theprojectiles launch we can find the answer for the initial velocity of the stone is:

            v = 17.71 m / s

A moderate-magnitude earthquake in Mexico City may cause a catastrophe rather than a disaster because of its high population density and vulnerability of infrastructure.

When it comes to earthquakes, the severity of the impact depends not only on the magnitude of the quake but also on the population density and the vulnerability of the infrastructure in the affected area. In the case of Mexico City, a moderate-magnitude earthquake can potentially result in a catastrophe due to several factors.

Firstly, Mexico City is one of the most densely populated cities in the world. With millions of people residing in a relatively small area, the potential for loss of life and injuries increases significantly. The high population density also makes evacuation and rescue operations more challenging, potentially leading to delays in providing necessary aid to those affected.

Secondly, the vulnerability of the infrastructure in Mexico City plays a crucial role. The city is situated in a highly seismic zone and has a history of devastating earthquakes. Despite efforts to strengthen buildings and improve regulations, many structures, particularly older ones, may still lack adequate seismic resistance. This increases the likelihood of buildings collapsing or suffering severe damage, posing a significant risk to the population.

Furthermore, the unique geology of Mexico City exacerbates the impact of earthquakes. The city is built on a former lakebed, which amplifies the shaking during seismic events. This phenomenon, known as liquefaction, can cause buildings and infrastructure to sink or tilt, further worsening the damage.

In conclusion, a moderate-magnitude earthquake in Mexico City has the potential to cause a catastrophe rather than a disaster due to its high population density and the vulnerability of its infrastructure. The combination of these factors amplifies the risk to human life and the difficulties in responding effectively to the aftermath of the earthquake.

An earthquake in Mexico City with a moderate magnitude may cause a catastrophe rather than a disaster because of the city's high population density and vulnerability to seismic activity.

The combination of a large number of people and infrastructure in a relatively small area increases the potential for extensive damage and loss of life. Additionally, Mexico City is built on soft soil, which amplifies the shaking during an earthquake. These factors contribute to the increased likelihood of a catastrophic event.

Answer:

The bright blue and black colors represent the following:

Constructive and destructive interference are represented by the blue and black colors, respectively. When two water waves collide constructively, the resultant wave is bright blue, while when they collide destructively, the resultant wave is black in color.

Explanation:

   When two propagating waves with the same frequency (say, \(\nu\)) and wavelength (say,\(\lambda\)) but slightly different amplitudes (say, A 1 and A 2) traveling in the same direction interfere or are superimposed on each other (that is incident at the same point or object), a third resultant wave with a different amplitude (increased or decreased) but same wavelength and frequency is generated.  

The direction difference between the two waves determines whether they intervene constructively (increasing the amplitude of the resultant wave) or destructively (increasing the amplitude of the resultant wave) (decreased amplitude of the resultant wave). To put it another way, when the difference in direction between the two waves is of the form -

      \(\Delta x = n\lambda , n=0,1,2,.....\) is the order of interference.

The two waves are then assumed to be in phase, and the interference is constructive, resulting in the resultant wave having a larger amplitude (which is the sum of the two amplitudes \(A_1 +A_2\)  also known as a maxima). When the difference in direction between the two waves is in the form -

  \(\Delta x = (2n-1)\frac{\lambda}{2} , n=0,1,2,.....\) is the order of interference.

The two intervening waves are then said to be out of phase, and the interference is disruptive, resulting in the resultant wave having a lower amplitude (which is the difference between the two amplitudes \(A_1+A_2\), also known as a minima).

Hence , the graphical representation of constructive (blue )and destructive (black) is attached.

π/10 rads

Explanation:

It takes an hour (60 minutes) for the minute's hand to turn a full circle or achieve an angular rotation of

2πl rad.

Now, number of periods of 3 minutes in an hour is;

Number of periods = 60/3 = 20 periods

Thus, 3 minutes rotation accounts for 1/20 of 2π the rotation of the minute's hand in an hour.

Thus;

Angular displacement = (1/20) * 2π = π/10 rads

Kisses' power is approximately 490.13 Watts.

Power (P) is defined as the rate at which work is done. The formula to calculate power is:

P = W / t

P is the power,

W is the work done,

t is the time taken.

The work done (W) can be calculated as the product of force (F) and distance (d):

W = F * d

In this case, the force is the weight of Kisses, which can be calculated using the formula:

F = m * g

m is the mass of Kisses,

g is the acceleration due to gravity (approximately 9.8 m/s^2).

m = 57 kg

d = 28 m

t = 32 seconds

g = 9.8 m/s^2

First, calculate the work done:

W = F * d

W = (m * g) * d

Next, calculate the power:

P = W / t

Substituting the given values:

W = (57 kg * 9.8 m/s^2) * 28 m

W ≈ 15684.24 J

P = 15684.24 J / 32 s

P ≈ 490.13 W

Therefore, Kisses' power is approximately 490.13 Watts.

Since the baseball is moving, it has kinetic energy.

Since the baseball has a certain height (it's not moving on the ground, it's moving above the ground), so it also has gravitational energy.

The ball itself has a certain temperature and has a molecular structure that holds energy, so the ball has internal energy.

And the ball has a certain deformation, that holds some elastic energy.

Therefore the correct option is B.

Potential energy is stored in the elastic material when we stretch it by some distance.

The energy stored when a force is used to deform an elastic object is called elastic potential energy. The energy is conserved until the force is released and the object returns to its original shape, doing work in the process. Objects can be compressed, stretched, or twisted when deformed.

Elastic material produces elasticity when stretched or compressed. The more the material is crushed or stretched, the greater this force.

Springs have many applications, including bed springs.

b) All the other motions are circular motion except the heart beat in a healthy person, which is periodic.

c) The motion of an apply falling from a tree is the only motion under the complete influence of gravity from the onset till the end.

The correct answer is a) low heat of vaporization.

The heat of vaporization is the amount of heat energy required to convert a substance from its liquid phase to its vapor phase at a constant temperature and pressure. Strong intermolecular forces result in a higher heat of vaporization because more energy is needed to overcome these forces and separate the molecules in the liquid phase.

Low heat of vaporization indicates that the intermolecular forces in the liquid are weak, allowing the molecules to easily escape into the vapor phase. Therefore, the presence of strong intermolecular forces would be indicated by a high heat of vaporization, not a low one.
