Two alarm sirens are emitting a loud note: at points between the two sirens the sound is very loud, but at other points it is much fainter. what wave phenomena described ​

Answers

The wave phenomena described in this scenario is known as interference.

Interference occurs when two or more waves interact with each other, resulting in the reinforcement or cancellation of the waves at certain points in space.

In this case, the two alarm sirens are emitting sound waves that are overlapping and interfering with each other. When the waves from the sirens are in phase, meaning their peaks and troughs align, constructive interference occurs. Constructive interference leads to the amplification of the sound waves, resulting in a louder sound at points between the two sirens.

On the other hand, when the waves from the sirens are out of phase, meaning their peaks and troughs are misaligned, destructive interference occurs. Destructive interference leads to the cancellation of the sound waves, resulting in a fainter sound at points where the waves interfere destructively.

The loud and faint regions of sound between the two sirens are a result of the constructive and destructive interference of the sound waves emitted by the sirens, respectively.

B.A light wave moves faster than most waves.

C.A light wave does not have a wavelength.

D.A light wave travels through the vacuum of space.

Answers

D. A light wave travels through the vacuum of space.

Explanation:
Mechanical waves require a medium to propagate, meaning they must have something to travel through. Examples of media for mechanical waves include solids, liquids, and gases. Light waves, on the other hand, are electromagnetic waves that can travel through a vacuum, meaning they do not require a medium to propagate. This is why light waves are not considered mechanical waves.

A vector number known as velocity describes "the pace at which an item changes its location." Imagine a person moving quickly, taking one stride ahead, one step back, and then beginning from the same place each time. A vector quantity is velocity. As a result, velocity is aware of direction. One must consider direction while calculating an object's velocity. Saying that an item has a velocity of 55 miles per hour is insufficient. The direction must be included in order to adequately characterize the object's velocity. Simply said, the velocity vector's direction corresponds to the motion of an item.

Two students sit in a sled and slide down a hill which gives them an initial horizontal velocity of 9.2 m/s. Their combined mass is 120 kg and the coefficient of friction between the sled and the snow is 0.23. How far will they slide horizontally before coming to a stop?

Answers

The sled will slide horizontally a distance of 18.94 m before coming to a stop.

The horizontal motion of the sled is under the influence of frictional forces acting opposite to the direction of motion. When the sled comes to rest, the frictional force would have done work to bring the sled to a halt.

To find the distance the sled would move, use the work-energy theorem which states that the work done by all the forces acting on a body is equal to the change in the kinetic energy of the body.

Kinetic energy = 1/2mv²where m is the mass and v is the velocity of the body

Initial velocity of the sled = 9.2 m/s

Mass of the sled and students = 120 kg

Coefficient of friction = 0.23There is no vertical motion so the potential energy remains constant and is ignored.The sled starts with kinetic energy equal to the work done by all the forces acting on it. The frictional force does negative work and removes the kinetic energy and bring the sled to a stop.Work done by friction = force × distance.

The force of friction is proportional to the normal force acting on the sled. We do not know the normal force acting on the sled, but we know the gravitational force acting on the sled and this gives the normal force.Force of gravity = mass × acceleration due to gravity = mg.

The normal force = force of gravity × cos (0) = mg × cos (0) = mg.

The angle between the horizontal and the slope is zero, so the angle of inclination is zero.

Work done by friction = force of friction × distance

Work done by friction = frictional force × distance

Work done by friction = μmg × distance

Work done by friction = kinetic energy at start of slide = 1/2mv²

Work done by friction = (1/2)(mass)(initial velocity)²

Work done by friction = (1/2)(120 kg)(9.2 m/s)²

Work done by friction = 5 137.6 J

Frictional force = μmg

Frictional force = (0.23)(120 kg)(9.8 m/s²)

Frictional force = 270.96 N270.96 N × distance = 5 137.6 J

distance = 5 137.6 J/270.96 N

distance = 18.94 m

Therefore, the sled will slide horizontally a distance of 18.94 m before coming to a stop.

OB. The amplitude increases.
OC. The wave speed decreases.
OD. The wahe speed increases

Answers

If two waves in the same space interfere completely constructively, the amplitude increases.

What is amplitude of a wave?

It is the maximum displacement moved by the wave from its point of equilibrium.

The constructive interference in the two waves occurs when both the waves come together and this results in them being in phase with each other. This means that the oscillation at the given point are in the same direction and due to this the resulting amplitude is larger than the amplitude of the particular wave. Constructive interference can produce a significant increase in the amplitude. For example: if 100 waves of equal amplitude interfere constructively, then the amplitude is 100 times more than the actual amplitude of the wave.

As the name states, the cars of a roller coaster really do coast along the tracks. A motor pulls the cars up a high hill at the beginning of the ride. After the hill, however, the motion of the car is a result of gravity and inertia. As the cars roll down the hill, they must pick up the speed that they need to whiz through the rest of the curves, loops, twists, and bumps in the track. To learn more about designing roller coasters, read the interview with Steve Okamoto.
How did you become a roller coaster designer?
I have been fascinated with roller coasters ever since my first ride on one. I remember going to Disneyland as a kid. My mother was always upset with me because I kept looking over the sides of the rides, trying to figure out how they worked. My interest in finding out how things worked led me to study mechanical engineering. What sort of training do you have I earned a degree in product design. For this degree, I studied mechanical engineering and studio art. Product designers consider an object's form as well as its function.They also take into account the interests and abilities of the
product's consumer. Most rides and parks have some kind of theme, so I must consider marketing goals and concerns in my designs.
What is the nature of your work?
To design a roller coaster, I study site maps of the location. Then, I go to the amusement park to look at the actual site.Because most rides I design are for older parks (few parks are built from scratch), fitting a coaster around, above, and in
between existing rides and buildings is one of my biggest challenges. I also have to design how the parts of the ride will work together. The towers and structures that support the ride have to be strong enough to hold up a track and speeding cars that are full of people. The cars themselves need special wheels to keep them locked onto the track andseat belts or bars to keep the passengers safely inside. It's
like putting together a puzzle, except the pieces haven't
been cut out yet.
What advice do you have for a student who is interested in designing
roller coasters?
Studying math and science is very important. To design a successtulcoaster, I have to understand how energy is converted from one form to another as the cars move along the track. I have to calculate speeds and accelerations of the cars on each part of the
track. They have to go fast enough to make it up the next hill! I rely on my knowledge of geometry and physics to create the roller coaster's curves.loops, and dips. Sammrazie in two paragraphs

The researcher is studying the amount of trash (in kgs per person) produced by households in city X, and previous research suggests that the amount of trash follows a distribution with density force fe (2) --1/7 torz.

The density function fe (2) --1/7 torz indicates the probability distribution of the amount of trash produced by households in city X. This means that the researcher can use this distribution to make predictions about the amount of trash that is likely to be produced by households in the city. The density function can be used to calculate the probability of producing a certain amount of trash per person, given the distribution.

A probability density function is a function that describes the likelihood of a continuous random variable taking on a specific value within a given range. In this case, the continuous random variable is the amount of trash (in kgs per person) produced by households in city X. The pdf provided in the question, f(e) = 1/7 for 2 ≤ e ≤ 9, indicates that the amount of trash follows a uniform distribution between 2 and 9 kgs per person.

When a ray of light enters a glass lens surrounded by air, it slows down.
Part A:As it leaves the glass, does its speed increase, decrease, or stay the same?
Part B:Choose the best explanation from among the following:
The speed will stay the same because the speed of light is a universal constant.
The speed decreases because the speed of light decreases whenever light moves from one medium to another.
Its speed increases because the ray is now propagating in a medium with a smaller index of refraction.

Answers

Answer:

Its speed increases because the ray is now propagating in a medium with a smaller index of refraction.

Explanation:

the maximum speed of light (in a vacuum) is an universal constant in our universe (as even that is a specific medium : the space-time-continuum). not its actual speed at a specific moment and place (and medium).

so, it can never ever go faster than that. but it will adjust down and then back up again, when it enters and leaves a different medium.

see it that way : the light we see today was generated at the core of the sun. it had to literally squeeze through the rest of the sun to reach the sun's surface. it took it at least 4000 years (!) but up to hundreds of thousands of years to get there. because of the medium that is the sun.

once it reached the surface of the sun and the open vacuum of space, it broke free, "cheered" in relieve and went light speed. and then almost 8.5 minutes later it reached Earth (depending on the season or where the Earth is on its elliptical path around the sun).

When a ray of light enters a glass lens surrounded by air, it slows down due to the change in its direction caused by refraction. As the ray of light exits the glass lens and returns to the air, its speed increases.

This is because the refractive index of air is lower than that of glass, and therefore the speed of light is faster in air. The best explanation for this is: "Its speed increases because the ray is now propagating in a medium with a smaller index of refraction." This statement is consistent with the laws of refraction and the relationship between the speed of light and the refractive index of a material. In summary, when a ray of light enters a glass lens surrounded by air, it slows down due to refraction. As it exits the lens and returns to air, its speed increases due to the difference in refractive indices between the two media. Understanding the behavior of light in different media is important for a wide range of scientific and technological applications.

Answers

The period of the system with the original mass, but with a spring that had a stiffness constant that was two times the stiffness constant of the original spring would be half of the original period.

This is because the stiffness of a spring is inversely proportional to its period, so doubling the stiffness of the spring will halve the period of the system.

When a spring is attached to a mass, the period of the system is determined by the mass and the stiffness of the spring. The period of the system is the time it takes for the mass to complete one full cycle of oscillation. As the stiffness of the spring increases, the period of the system decreases.

Telling customers they will receive a free cookie with their hamburger had a significant effect on the amount they say they are willing to pay for a hamburger, z = 3.68, p < .05. b. Telling customers they will receive a free cookie with their hamburger did not have a significant effect on the amount they say they are willing to pay for a hamburger, z = 4.04, p > .05. c. Telling customers they will receive a free cookie with their hamburger had a significant effect on the amount they say they are willing to pay for a hamburger, z = 3.60, p < .05. d. Telling customers they will receive a free cookie with their hamburger did not have a significant effect on the amount they say they are willing to pay for a hamburger, z = 3.60, p < .05Compute the estimated Cohens d to measure the size of the treatment effect.Note: Cohens d is always reported as a positive value and reflects the proportion of the standard deviation that is affected by the treatment.Estimated Cohens d = Using Cohens criteria, the estimated Cohens d indicates that telling customers they will receive a free whistle is associated with a in the amount they are willing to pay for the hamburger. a cab company charges a flat rate of $2 plus an additional $0.50 for every mile traveled .use this information for items 12 and 13 . a.write an expression that can be used to determine the total cab fare for a distance of m miles. b.when sara arrived at her destination ,her cab fare was $7.50..write an equation to represent this situation .how many miles did sara travel?
