Answer:
H2SO4 ( Sulfuric Acid ) + NaOH ( Sodium Hydroxide ) > Na2SO4 ( Sodium Sulfate ) + H2O ( Water )
Explanation:
Answer:
Wavelength, λ = 6.7 x 10^-11 m
Explanation:
Frequency and wavelength are inversely proportional to each other.
In this problem;
f = 4.5 x 10^18 Hz
wavelength, λ = ?
Speed of light, c = 3 x 108 m/s.
These variables are related by the following equation;
c = λ * f
Making λ subject of focus, we have;
λ = c / f
λ = 3 x 10^8 / 4.5 x 10^18
λ = 0.67 x 10^-10
λ = 6.7 x 10^-11 m
Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20
I would say #3 I’m sorry if it’s wrong tho
