An u do number 10 and show all the steps for it please answers are in the bottom

It get SPH3U Universal Wave Equations 10. You are shouting in a monotone voice with a frequency of 440 Hz. Your friend is 300 m away. If the speed of sound waves is 344 m/s, how many wavelengths occur between you and your friend? 11. This full scale diagram shows a series of wave crests. Successive crests pass a given point in 0.5 s. a) What is the amplitude of this wave? (measure this) b) What is the wavelength in centimetres? (measure this) c) What is the frequency? d) What is the velocity of the waves? 12. A given crest of a water wave requires 5.2 s to travel between two points on a fishing pier located 19 m apart. It is noted in a series of waves that 20 crests pass the first point in 17s. What is the wavelength of the wave? (A diagram would help) 13. Two men are fishing from small boats located 30 m apart. Waves pass through the water, and each man's boat bobs up and down 15 times in 1.0 min. At a time when one boat is on a crest the other one is in a trough, and there is one crest between the two boats. Draw a well labelled diagram. What is the speed of the waves?
