How many minutes and seconds worth of songs do you have?
PolarNik [594]

Question 1:

48 + 63 + 28 + 44 + 43 = 226 minutes

41 + 40 + 15 + 1 + 39 = 136 seconds

136 seconds = 2 minutes and 16 seconds

The answer is 228 minutes and 16 seconds.

Question 2: 228 minutes = 3 hours and 48 minutes

The answer is 3 hours and 48 minutes, but if you're also counting seconds, add 16 seconds to the end of it.

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
