Local radio station WMMM-FM (Triple M), bills itself as the "Sound of Madison". Its radio waves are broadcast at a frequency of

105.5 MHz (megahertz). What is the wavelength (in meters) of Triple M’s radio broadcast waves? Report your answer to 4 significant figures. (c = 2.998 x 108 m/s)

Answer: wavelength= 2.842m

Explanation:

wave speed C= frequency × wavelength

Wavelength= C/ frequency

= 2.998× 10exp8/ 105.5×10exp6Hz

Wavelength= 2.842m

Goodluck...

Light from a helium-neon laser (λ=633nm) passes through a circular aperture and is observed on a screen 5.80 mm behind the apert
Helga [31]

Explanation:

Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.

So by using the equation of diffraction,

dsinA = nL

SinA is a geometric component it can be written as,

d\frac{y}{x} = nL

∵ x is the distance from screen.

∵ y is the half of the width of central maximum.

now by putting the values in mm,

d\frac{17}{5.80} = 0.000633

d = 2.15×10^{-4} mm

Two long, parallel wires each carry the same current I, but the two currents are anti-parallel. The two wires are a distance r a
Georgia [21]

Answer:

8 x 10⁻⁷ x  I / r

Explanation:

Two parallel long wires are carrying current I . Let the direction be towards the right in the farthest and towards the left in the nearest. Magnetic field due to current I  at a  distance d is given by the expression

B = μ₀ 2 I / 4π d

I the present case distance d = r/2  

Magnetic field due to one wire at point d = r/2  is

B₁ = μ₀ 2 I / (4π r / 2 )

= 10⁻⁷ x 4I / r

Magnetic field due to the other wire at point d = r/2  is

B₂ = μ₀ 2 I / (4π r / 2 )

= 10⁻⁷ x 4I / r

Direction of magnetic field due to both the wires at the mid  point P will be same . It will be in downward direction in the given scenario

So total magnetic field

B = B₁ + B₂

= 2 x  10⁻⁷ x 4I / r

= 8 x 10⁻⁷ x  I / r

W=2485.65 J ,work did the movers do friction force a 41.0- kg crate 10.3 m across a rough floor without acceleration

<h3>What is a basic friction force?</h3>

Two surfaces that come into contact and slide against one another produce a force known as frictional force. Several aspects that influence the frictional force include: The surface texture as well as the amount of force attracting them together have the most effects on these forces.

<h3>What outcomes does friction produce?</h3>

It generates heat, which is useful for warming our bodies or specific areas of any object. Power is also lost as a result. It makes noise during every operation. We are able to walk, run, dance, etc. due to friction.

Which statement is true of a wave that’s propagating along the pavement and girders of a suspension bridge?
Readme [11.4K]
Had to look for the options and here is my answer.
The statement that is considered correct regarding a wave that is propagating along the pavement and girders of a suspension bridge is this: "t<span>he wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions." Hope this helps.</span>
