V (speed) = F (frequency) x Wavelength
If we rearrange the formula, making frequency the subject;
F (frequency) = Speed ÷ Wavelength
F = 300,000 m\s x 4.5 e -10m
F = 0.08810409956 Hz

One small reason would be renewable resources can be used more and never lose supply on the other hand non-renewable resources will one day run out
As we know that acceleration is given as

here we know that



now we will have


so acceleration will be 3 m/s^2
