As we know so far, c = f / λ. This equation comes from a much simpler version of speed = distance/ time. As the λ  (with units "m") can be seen as distance and the frequency (with units "...

x = 4.5 

Rearrange the equation, so that like terms are on the same side:

5x - 3x = 2 +7

2x = 9

Then to find x, divide 9 by 2

x = 4...

This is the minimum amount of energy reacting particles must have to undergo a chemical reaction.

It can lead to an increase in the population size of strains of antibiotic-resistant bacteria, such as MRSA
