Wavelength = (speed)/(frequency) = 300,000,000/120,000,000 = 2.5 meters
the answer is in the picture ok
good luck don't worry it's a correct
#carry on learning
Distance is how far something moves in a specific amount of time.
Answer:
Forces that the rider applies to the pedals, saddle and handlebars during speeding, hill climbing and starting are estimated from cine film records using elementary mechanics. The results are compared with force measurements obtained from an instrumented pedal. Pedal forces of up to three times bodyweight were recorded during starting. Handlebar loads were always significantly large.
