By definition we know that we can calculate the frequency of an electromagnetic wave by wavelength, using the following equation:
Where:
λ is the wavelength.
c is the speed of light
f is the frequency.
Then:
So:
We know that the speed of light is:
So:
Finally, the frequency is
6.2727422 miles per second
-- If you're adding, no.
-- If you're subtracting, maybe. Sometimes but not always.
-- If you're multiplying or dividing, yes.
-- In grammar, yes, but it makes for a very awkward sentence.
<span>The correct option is: (A) 41 °F (5°C)
Explanation:
As the temperature increases (from 6-7 °C), the tendency of a bacteria to grow also increases. Therefore, it is recommended to keep the temperature of refrigeration units, salad bars and other cold items at 41 °F (5 °C) or colder. Hence, the correct answer is option (A).</span>
Answer:
B: Two vectors that do not lie along the same line.
