A radio station's channel, such as 100.7 fm or 92.3 fm, is actually its frequency in megahertz (mhz), where 1mhz=106hz and 1hz=1sâ1. calculate the broadcast wavelength of the radio station 104.1 fm.

Answers

In order to determine the wavelength, we use the wave equation:

speed = frequency * wavelength

speed of light c = 3 x 10⁸ m/s

Frequency f = 104.1 MHz = 1.041 x 10⁸ Hz

c = fλ
λ = c / f

λ = 3 x 10⁸ / 1.041 x 10⁸
λ = 2.88 meters

The wavelength of the waves is 2.88 meters.

a stone is thrown down off a bridge with a veloctiy of 5.6m/s. What is the velocity afer 3 seconds have passed?

Answers

I think it's 16.8 because you multiply 5.6x3=16.8

Answer:

Final speed of the stone, v = 35 m/s

Explanation:

It is given that,

Initial speed of the stone, u = 5.6 m/s

Let v is the velocity of the stone after 3 seconds have passed. It is moving down under the action of gravity. So, using the first equation of motion as :

[tex]v=u+at[/tex]

[tex]v=u+gt[/tex]

[tex]v=5.6+9.8\times 3[/tex]

v = 35 m/s

So, the final speed of the stone is 35 m/s. Hence, this is the required solution.

What are mixtures that have floating particles called? colloids emulsions solutions suspensions

Answers

Mixtures with floating particles are called suspensions, where larger particles don't dissolve and eventually settle. Examples include muddy water and orange juice with pulp.

Mixtures that have floating particles are called suspensions.

- Colloids: These are mixtures where particles are evenly dispersed but do not settle out. Examples include milk and fog.

- Emulsions: These are mixtures of immiscible liquids, like oil and water, where one liquid is dispersed throughout the other in the form of small droplets. Examples include mayonnaise and vinaigrette.

- Solutions: These are homogeneous mixtures where one substance (solute) is dissolved in another (solvent) at the molecular level. Examples include saltwater and sugar dissolved in water.

- Suspensions: These are heterogeneous mixtures containing large particles that will eventually settle out over time. Examples include muddy water and orange juice with pulp.

Since you asked for the one with floating particles, the correct answer is suspensions.

true or false:acceleration toward the center of a curved or circular path is called gravitational acceleration.

Answers

Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.

Centripetal acceleration is the acceleration of an object moving in a circle directed towards the center, as part of uniform circular motion.

Centripetal acceleration is the acceleration of an object moving in a circle, directed toward the center. It is always present in uniform circular motion, causing the object's velocity to constantly change direction.

Another name for prison or jail terms is which of the following? misdemeanors felonies laws sentences

Answers

Answer:D

Explanation:

Final answer:

The terms 'sentences' refer to the legal consequences imposed for committing a crime, including prison or jail time. Misdemeanors typically lead to shorter jail sentences, whereas felonies can result in longer incarceration in prison. Alternative sentencing options are also available, such as probation or rehabilitation.

Explanation:

Another name for prison or jail terms is sentences. A sentence is the formal legal consequence imposed by a court upon a person who is convicted of a crime. Misdemeanors are less serious crimes compared to felonies, and they often result in incarceration for one year or less, which typically occurs in a local jail rather than a state or federal prison. Felonies are more serious crimes and can lead to longer periods of incarceration in state or federal prisons. Alternative sentencing options, such as probation, rehabilitation, or home confinement, might also be used instead of jail time, particularly in the case of misdemeanors.

Prisons and jails serve different purposes; jails typically house individuals awaiting trial or serving short sentences, while prisons are for those serving longer sentences. The choice between sentencing someone to jail or prison often depends on the severity of their crime and the length of the sentence imposed.

If vx = 3 meters/second and vy = 4 meters/second, what is the magnitude of the resultant velocity?

Answers

The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. We use the pythagorean theorem for this case. We do as follows:

vR^2 = vx^2 + vy^2
vR = √3^2 + 4^2
vR = 5 m/s

Answer

5m/s

Explanation:

Resultant is defined as the single velocity/forces that balances all other velocities/forces acting on a body. It is also defined as the vector sum of the vectors acting on a body.

Given two vectors in the x and y direction i.e Vx = 3m/s Vy = 4m/s

The formula of the resultant of both vectors will be;

R²= Vx² + Vy²

Where R is the resultant vector

R²= 3²+4²

R²=9+16

R²=25

R=√25

R=5m/s

Therefore, the magnitude of the resultant velocity is 5m/s

Classic mode (the only mode in IIS6 and below) is a mode where IIS only works with ISAPI extensions and ISAPI filters directly. In fact, in this mode, ASP.NET is just an ISAPI extension (aspnet_isapi.dll) and an ISAPI filter (aspnet_filter.dll). IIS just treats ASP.NET as an external plugin implemented in ISAPI and works with it like a black box (and only when it's needs to give out the request to ASP.NET). In this mode, ASP.NET is not much different from PHP or other technologies for IIS.

Integrated mode, on the other hand, is a new mode in IIS7 where IIS pipeline is tightly integrated (i.e. is just the same) as ASP.NET request pipeline. ASP.NET can see every request it wants to and manipulate things along the way. ASP.NET is no longer treated as an external plugin. It's completely blended and integrated in IIS. In this mode, ASP.NET HttpModules basically have nearly as much power as an ISAPI filter would have had and ASP.NET HttpHandlers can have nearly equivalent capability as an ISAPI extension could have. In this mode, ASP.NET is basically a part of IIS.

Sarah wanted to know the velocity of an airplane traveling from Houston to Dallas. After recording the distance (in miles) and time (in hours) it took to travel to Dallas, what other measurement does Sarah need to determine the airplanes velocity?

Answers

She would need to know the direction that the plane took. Velocity is a vector so it needs a speed which she has by having the distance and time it took to travel, but a vector also has direction in addition to it.

Sarah needs to know also the direction of the airplane.

In fact, the velocity of an object is a vector, which means it has

a) a Magnitude (the speed)

b) a direction

Knowing the distance and the time, Sarah is only able to calculate the speed (which is the magnitude of the velocity), given by

[tex]v=\frac{distance}{time}[/tex]

but in order to give complete information about the velocity, she also needs to know the direction of the airplane.


in which of these reaction is energy released
all reactions
no reactions
endothermic
exothermic

Answers

Your answer is: exothermic. We can figure this out by breaking up the word: Exo=out and Thermic=heat (type of energy). Meaning heat energy is being released, meaning your answer is exothermic. 

The correct answer is D. Exothermic

Explanation:

One of the features used to classify reactions is whether energy is released or absorbed during them. In this way, when the reaction causes energy to be absorbed this is classified as endothermic; an example of this is when an ice cube melts because it absorbs heat from the environment. On the other hand, if energy is released, the reaction is exothermic; for example, fire releases heat, and therefore this reaction is exothermic. According to this, it can be concluded not all reactions release energy but only exothermic reactions.

What is scientific investigation?

Scientific investigation is the process of looking for answers by doing extensive research and finding the answers through experimental results.

The scientific investigation very much relies on true experimental results that can be supported by evidence.

As theories and propositions are developed, tested against observations of the natural world throughout time, and refined in response to new information and findings, scientific knowledge is accumulated.

Conducting observations about the natural world is how science learns. A discovery could spark a hypothesis-generating scientific inquiry. Experiments can be used to verify the theory. The outcomes of experiments alter our understanding of science.

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen window, and one on the mantel in the living room. Each plant has the same size pot and the same soil, and Lauren gives each plant the same amount of water. What are the dependent and independent variables? Your answer:

Answers

First, before determining which variable is which, we go over the definition of each.
The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable.
The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable.

In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.
Final answer:

The dependent variable in Lauren's experiment is the growth of the African violets, and the independent variables are the locations of the plants. Other growth factors like watering, plant food, soil amount, and soil type should be controlled to ensure the experiment's accuracy.

Explanation:

In Lauren's situation with the African violets, the dependent variable is the growth or health of the plants, since it is what she is observing and measuring in response to the different conditions. The independent variables are the locations where the plants are placed (balcony, kitchen window, mantel in the living room), as these are the conditions that Lauren is changing to see how they affect the growth of the African violets.

To have a controlled experiment, Lauren should keep other factors constant that may affect plant growth, such as the amount of water (which she is already controlling), the amount of plant food, the amount of soil, and the type of soil.

If Lauren's experiment were setup like Gary's - with a focus on the amount of sunshine - she might control for things like individual plant variation, soil temperature due to different colors of containers, water loss due to evaporation from the soil, and the effect of insects which may attack one set of plants but not another.
