An FM radio station broadcasts at 84 megahertz (MHz). What is the energy of each photon in Joule? Use h = 6.6 * 10 ^ (- 34) * j

iragen [17]

Answer:

$E=5.544*10^{-26} J$

Step-by-step explanation:

The equation for photon energy is given by:

$E=hf$

Where:

$h=Planck\hspace{3}constant=6.6*10^{-34} \\f=Frequency\hspace{3}of\hspace{3}the\hspace{3}wave=84000000Hz$

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.

So, replacing the data provided in the previous equation:

$E=(6.6*10^{-34} )*(84000000)=5.544*10^{-26} J$

Moesha has 196 pepper plants that she wants to plant in square formation. How many peppers plants should she plant in each row?

miss Akunina [59]

Hey there!!

In order to solve this question, we take the area as 196 as these are the total number of plants to cover a specific place.

The formation must be in a square formation

area of a square = ( s ) ²

s = side

or the number of plants in a row

s² = 196

s = √196

s = 14

There are 14 plants in each row

Hope my answer helps!
