Answer:
Wavelength and frequency are inversely related.
Explanation:
-Longer waves have lower frequencies.
-Shorter waves have longer frequencies.
-This simply implies that that as the length of the wavelength increases it's frequency reduces.
Momentum = (mass) x (speed)
Momentum = (12,000 kg) x (40 m/s)
Momentum = (12,000 x 40) kg-m/s
<em>Momentum = 480,000 kg-m/s </em>
