a sound wave has a frequency of 3000hz what is the edistance btweeeen crests of the wavbe

Sound is transmitted through gases, plasma or blood, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.

For example, when you flick the rim of a glass, the glass will vibrate imperceptibly. These vibrations move through the air and strike the ear drum of anyone within hearing range (click here to find out 'How Our Ears Hear'). In fact, these vibrations, or sound waves, can move through any medium: gas, liquid or solid.

It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.

The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions.  The higher the electron affinity is, the more the neutral atom wants to gain electrons.

The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell.

That means that they want to form cations (loose electrons).  Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration.  That means that it forms anions.

Therefore, It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.

Answer:

1) The distance further it takes Peter to arrive at the Coffee shop than Mia is 1.24 km

2) Mia's average speed is 6.00 km/hour

Peter's average speed is 8.48 km/hour

4) Mia's average velocity = Peter's average velocity = 6.00 km/hour

Explanation:

The given information from the diagram are;

The distance Peter jogs from school to the flower shop = 2.00 km

The distance Peter jogs from the Flower shop to the Coffee shop = 2.24 km.

The distance Mia walks from school directly to the Coffee shop = 3.00 km

The time it takes both Peter and Mia to arrive at the coffee shop = 30 minutes = 0.5 hour

1) The total distance Peter travels from school to the Coffee shop = 2.00 km + 2.24 km = 4.24 km

The distance Mia travels from school to the Coffee shop = 3.00 km

The distance further it takes Peter to arrive at the Coffee shop than Mia = 4.24 km - 3.00 km = 1.24 km

The distance further it takes Peter to arrive at the Coffee shop than Mia = 1.24 km

2) [tex]Average \ speed = \dfrac{Total \ distance \ traveled}{Total \ time \ taken \ in \ the \ journey}[/tex]

[tex]Therefore, \ Mia's \ average \ speed = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]

Mia's average speed = 6.00 km/hour

[tex]Peter's \ average \ speed = \dfrac{4.24 \ km}{0.5 \ hour}= 8.48 \ km/hour[/tex]

Peter's average speed = 8.48 km/hour

4) [tex]Average \ velocicty = \dfrac{Displacement }{Time \ taken}[/tex]

The displacement from the School to the Coffee shop is 3.00 km for both Mia and Peter

The time it takes both Peter and Mia to arrive at the Coffee shop from the school is 30 minutes = 0.5 hour

[tex]Therefore, \ Mia's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]

Mia's average velocity = 6.00 km/hour

[tex]Peter's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]

Therefore, Peter's average velocity is also = 6.00 km/hour

Answer:a. 24 kg m/s

b.  3/5s

Explanation:

a.impulse is the change in momentum so at first the momentum is zero because the ball was at rest and the final momentum is 1.2kg*20m/s=24 kg m/s

so the impulse would be (24-0) kg m/s=24 kg m/s

b. so the impulse equation is impulse is force *delts time

so 24 kg m/s=40N*t

t=24 kg m/s /40N=3/5 s

Answer:

Answer:

1

Explanation:

Impulse = change in momentum = force x change in time

50 x 0.02 = 1

If a baseball is hit by a bat with a force of 50N during a time interval of 0.02s. Then the impulse on the baseball is 1 N s.

An impulse is a quantity that measures the change in momentum of an object. It is defined as the product of force and time, and it is measured in units of Newton seconds (N s) or kilogram meters per second (kg m/s). The impulse experienced by an object is equal to the change in momentum that occurs when a force is applied to it for a specific period of time.

Impulse is practically applied in various areas of physics and engineering. Here are a few examples:

Sports: Impulse is a crucial factor in many sports, especially those that involve hitting or throwing objects. In sports like baseball, cricket, and golf, the force and time of impact determine the ball's momentum and trajectory.

Transportation: The impulse experienced by vehicles during a collision is used to determine the forces that act on the occupants. This information is used to design safety features such as airbags and crumple zones.

Engineering: In mechanical engineering, impulse is used to design machines that can produce large forces over short periods. For example, hydraulic presses use a large force over a short period to shape metal or other materials.

Physics: Impulse is a fundamental concept in physics, particularly in the study of collisions and the conservation of momentum. The impulse-momentum theorem is a fundamental law of mechanics that relates the change in momentum of an object to the impulse applied to it.

Here in the Question,

The impulse on the baseball can be calculated using the formula:

Impulse = Force x Time

Given that the force is 50 N and the time interval is 0.02 s, the impulse can be calculated as follows:

Impulse = 50 N x 0.02 s

Impulse = 1 N s

Therefore, the impulse on the baseball is 1 N s.

Answer:

D. When a chemical reaction releases energy, it is an example of an endothermic reaction.

Explanation:

"Endo" means within. Therefore, an endothermic reaction releasing energy makes no sense.

p.s.

I owe you for your help.

Thank you so much!

The statement that is not true about the chemical reaction is when a chemical reaction releases energy, it is an example of an endothermic reaction, therefore the correct answer is option D.

A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Substances with novel characteristics are created through chemical reactions.

Products of chemical reactions differ from the reactants in terms of their features.

Chemical bonds may break or produce new ones during interactions.

The excess energy is released during an exothermic reaction, making the potential energy of the reactant higher than the potential energy of the product. The right response is D.

The two charged particles will have Opposite charge.

According to Coulomb's law: The magnitude of each of the electric forces with which two point-at-rest charges interact is directly proportional to the product of the magnitude of both charges

And inversely proportional to the square of the distance that separates them and has the direction of the line that joins them.

The formula will be given as:

[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]

If the two charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.

Hence the two charged particles will have Opposite charge.

plz mark brainliest

Answer and Explanation:

A horseshoe-shaped magnet, that is, a "U" shape, has stronger attraction and repulsion capacities than that presented by a bar-shaped magnet. This is because the lines of the magnetic field on the "U" magnet are more dense and therefore promote a stronger magnetic field. This strong magnetic field exists because in a "U" shaped magnet, the magnetic poles are on the same plane, allowing a better fluctuation of the lines of the magnetic field.

Answer:

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.

we will use one of the kinematic equations :

d = u*t+0.5*a*t²

in which : d : distance

u : initial velocity

a : acceleration

t : time

after substitution :

initial velocity = 0 m/s (from rest)

2.8 = 0*t+0.5*7.14*t²

2.8 = 3.57*t²

t² = 0.7843

Answer:

The correct answer is B. a nucleus surrounded by electrons.

Answer:

I. Final velocity, V = 10m/s.

II. Distance, S = 10m.

Explanation:

Given the following data:

Acceleration = 5m/s²

Time = 2 seconds

Since the vehicle starts from rest, initial velocity = 0m/s

To find the final velocity, we would use the first equation of motion.

V = U + at

Substituting into the equation, we have

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m

C. The wavelength is longer.

A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it.

The air particles vibrate parallel to the direction of propagation.

A longitudinal wave consists of a repeating pattern of compressions and rarefactions.

Thus, the wavelength is commonly measured as the distance from one compression to the next adjacent compression or the distance from one rarefaction to the next adjacent rarefaction.

Longitudinal waves move through a medium from the point of the disturbance in the form of compressions (where particles of the medium are bunched together) followed by rarefactions (where particles of the medium are farther apart).

In longitudinal waves, the distance from one compression to the next is the wavelength.

Therefore,

In longitudinal wave the wavelength is longer.
