What do radio waves and microwaves have in common?

a both are at the ideological the spectrum that has the lowest frequency
b both are at the spectrum that has the shortest wavelengths
c both have higher frequencies than visible light

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18
