Answer:

2Hz

Explanation:

Find the diagram attached

Using the formula;

v = fλ

v is the velocity

f is the frequency

λ is the wavelength

Given the following

v = 3.2m/s

λ = 4.8/3 = 1.6m

Get the frequency

f = v/λ

f = 3.2/1.6

f = 2Hertz

Hence the frequency of the wave is 2Hz

The frequency of the wave is equal to 2.0 Hertz.

Given the following data:

To calculate the frequency of the wave​:

First  of all, we would determine the wavelength of the wave in the image attached below:

Note: Wavelength is the successive distance between two (2) crests.

[tex]Wavelength = \frac{distance}{3} \\\\Wavelength = \frac{4.8}{3}[/tex]

Wavelength = 1.6 meter.

Mathematically, frequency is given by this formula:

[tex]Frequency = \frac{velocity}{wavelength} \\\\[/tex]

Substituting the given parameters into the formula, we have;

[tex]Frequency = \frac{3.2}{1.6}[/tex]

Frequency = 2.0 Hertz.

Answer:

Explanation:

This is a displacement vector since it is given in terms of a distance (meters, to be specific). The way you find the x-component is:

[tex]V_x=Vcos\theta[/tex] which means you multiply the magnitude (length) of the vector times the cos of the direction (the angle):

Answer:

All matter is made up of atoms.

Answer: rarefaction

Explanation: correct answer on a p e x

Rarefaction term describes an area of low density in a longitudinal wave.

Wave is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave. Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave. Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a transverse in nature wave.  

In Longitudinal wave, wave carries energy and momentum with compression and rarefaction. Compression is region of high density, in this region particles of the medium is compressed. rarefaction is region of expansion and it is low density region of longitudinal wave.

Hence option C is correct.

Answer:

6.58×10⁶ F

Explanation:

Applying,

Q = CV..................... Equation 1

Where Q = charge of the capacitor, C = Capacitance of the capacitor, V = Volatage

Make C the subject of the equation

C = Q/V................. Equation 2

From the question,

Given: Q = 7.9×10⁷ C, V = 12.0 V

Susbtitute these values into equation 2

Answer:

Sentence III

Explanation:

I. It takes positive work to bring like charges together.

Using Coulom law we know that like charges will feel a repulsion force that meen that if we want to put them together we are going againt the force, this means we need a negative work. So is False.

II. Electric field lines always point in the direction of decreasing electric potential.

The elctrical fiels depend on the charge of the particle. So if the particle is positive the field will point always outwart the charge, and if the particle is negative, the electric field will point to the charge. Also, we know that the potential is bigger clouser to the charge, so this sentence is folce when we have a negative charge. So is False.

III. If a negative charge moves in the direction of the electric field, its potential energy decreases

If a negative particle move in the direction of the elctric field in bout cases the potential will decrease. If we have a positive charge the electron will be atracted by the field, How ever the electric fild is pointing in the other direction, for that reason will decrease.

61.62 N/m

Explanation:

Applying,

1/F = 2π[tex]\sqrt{m/k}[/tex].................. Equation 1

Where F = frequency, m = mass of the spring, k = spring constant, π = pie.

make k the subject of the equation

k = m(2πF)²............... Equation 2

From the question,

Given: m = 1.00 kg, F = 1.25 Hz

Constant: π = 3.14

Substitute these values into equation 2

k = 1(2×3.14×1.25)²

Answer:

-1m/s

Explanation:

We can calculate the speed of block A after collision

According to collision theory:

MaVa+MbVb = MaVa+MbVb (after collision)

Substitute the given values

5(3)+10(0) = 5Va+10(2)

15+0 = 5Va + 20

5Va = 15-20

5Va = -5

Va = -5/5

Va = -1m/s

Hence the velocity of ball A after collision is -1m/s

Note that the velocity of block B is zero before collision since it is stationary

Answer:

Mechanical Advantage of car jack is 20

Explanation:

During the day the sky looks blue because it's the blue light that gets scattered the most. It's redirected into many different directions all over the sky, whereas the other wavelengths aren't scattered as much. Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. White light is composed of seven light and among them, blue light scatters the most as the wavelength of the blue light is comparable to the size of particles in the atmosphere. So, the sky appears blue. Hence, the sky appears blue because the fine particles in the atmosphere scatter light of shorter wavelengths! :D
