The answer is false. It is because the electron structure of
the atom is not determined by using the direct observation of using an x-ray
but rather the usage of theoretical modeling and the emission spectra will be useful
in observing.
300 degrees Kelvin = 300 - 273 = 27 degrees Celsius.
So what you need to do is find out how many degrees Fahrenheit that is.
F = 9/5(27) + 32
F = 48.6 + 32
F = 80.6
You are at 55oF. You need to go from 55 to 80.6 or 25.6 degrees F.
Your closest answer is B. <<<<<< Answer
Answer:
A
Explanation:
There is a specific tool called an oil drill that drills into the ground and then a pipe sucks the oil up onto a vessle
Well there are 60 seconds in a minute and 60 minutes in an hour and 24 hours in a day so you would do 60×60 which is 3600. then you would multiply 3600 by 24 which would give you the number of seconds in a day, 86400. since you need the number of seconds in 2 days just multiply the amount by 2. your answer is: There are 172,800 seconds in two days.
