The speed of radio waves can be approximated to be 299,790,000 meters per second. The wavelength of a particular radio station’s

azamat

Answer:

$f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz$

And if we convert to megahertz we got:

$9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz$

Step-by-step explanation:

For any mechanical wave we have the following general relationship:

$v = \lambda f$

where:

v represent the speed of the wave = 299790000 m/s

$\lambda = 3.03m$ represent the wavelength for the radio station

f represent the frequency of interest

If we solve for the frequency we got:

$f = \frac{v}{\lambda}$

And replacing the values we got:

$f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz$

And if we convert to megahertz we got:

$9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz$

I will give branliest

Evgesh-ka [11]

Step-by-step explanation:

Height of ladder = 12ft .

Here perpendicular is height to which it reaches .

When angle is 30⁰ :-

=> sin 30⁰ = H/12

=> ½ = H/12

=> H = 12/2

=> H = 6m ( ans )

When Angle is 45⁰ :-

=> sin45⁰ = H/12

=> 1/√2 = H/12

=> H = 6*√2*√2/√2

=> H = 6√2 m ( ans )

When angle is 60⁰ :-

=> sin60⁰ = H/12

=> √3/2 = H/12

=> H = 12 *√3/2

=> H = 6√3 ( ans )

hope it helped !
