How many minutes would it take a radio wave to travel from the planet Venus to Earth? (Average distance from Venus to Earth is 28 million miles.)

$d i s \tan c e(m)=\left(2.8 \times 10^{7} m i\right) x \frac{1.61 \mathrm{km}}{1 \mathrm{mi}} \times \frac{1000 \mathrm{m}}{1 \mathrm{km}}$$=4.5 \times 10^{10} \mathrm{m}$$\min =\left(4.5 \times 10^{10} \mathrm{m}\right) \times \frac{1 \mathrm{s}}{3.00 \times 10^{8} \mathrm{m}}=1.5 \times 10^{2} \mathrm{s}$

In chemistry and physics, electronic structure is the way the electrons of an atom are arranged in relationship to the nucleus. It is determined by the subshells the electrons are bound to, which are in turn determined by the principal quantum number ("n") and azimuthal quantum number ("l"). The electrons within an atom are attracted to the protons in the nucleus of that atom. The number of electrons bound to the nucleus is equal to the number of protons in the nucleus, which is called the atomic number ("Z"). The electrons are attracted to the nucleus by this mutual attraction and are bound to the nucleus. The electrons within an atom are attracted to each other and this attraction determines the electron configuration. The electron configuration is described by the term symbol, which is the letter used to identify each subshell.

In physics, the wave–particle duality is the concept that every object or process, no matter how large or how small, behaves as both a wave and a particle. The wave–particle duality is one of the central concepts in quantum mechanics.

Okay, So this question asked, how long would it take in minutes for radio wave to travel from Venice to the earth? Now we know that according question, it is 28 million miles between Venus and Earth. So first, we need to invert that two meters because we know that speed of light, which is also the speed of an electromagnetic wave, is three times send the 80 meters percent. So we need to make sure that those air in the same units. So let's go ahead and say 28 and we're gonna say instead of saying 28 million with zeros one right, 28 times, 10 to the sixth miles, we're gonna convert 1st 2 kilometers. All right, so we know that there is for every one mile, there are 1.61 kilometers. Okay, so now if we were to stop here, we have been kilometers, but we wanted in meters. So we know that for every kilometer based on the the tens scale of the metric system, there will be 1000 meters, so that will give us when we plug that in. That would give us 4.5 times 10 to the 10th meters. That is a long way. So now we need So that's the distance. Now we need to know how long it's going to take. So like I said previously, for every, uh, radio waves are a form of electromagnetic wave and that has the same speed as a speed of light, which is three times 10 to the eighth meters per second. So if we want to go ahead and convert this to time, well, say 4.51 times 10 to the 10th meters times three times 10 to the eighth meters every second. This is the constant for the speed of light. Like I was saying, that will give us 150 seconds now weaken. From now, it's pretty easy to convert two minutes, considering we were just divide by 60. Just say 60 seconds in a minute. This will give us 2.5 minutes. So that is how long it takes a radio wave to travel from Venus to Earth. Thank you very much.
