I would like if these were done ASAP, please and than you!

Question 1 [1 point] Transverse Wave is 0 one which the medium is displaced perpendicular to the wave to direction of wave propagation, such as waves on a string. 0 one which the medium is displaced parallel to the wave to direction of wave propagation, such as waves on a string. 0 one which the medium is displaced perpendicular to the wave to direction of wave propagation, such as sound wave in air. 0 one which the medium is displaced perpendicular to the wave to direction of wave propagation, such as sound wave in air. Question 8 (1 point) The noise of thunder is heard 3 s after the flash of lightning. How far away is the place where lightning stuck? (Take the speed of sound to be 340 m/s.)Question 9 (2 points) A transverse wave travels in medium X with a speed of 800 m/s and a wavelength of 4 m. The wave then moves into medium Y, traveling with a speed of 1600 m/s. a. Determine the frequency of the wave in medium Y. (1 mark) b. Determine the wavelength of the wave in medium Y. (1 mark)Question 10 (2 points) Water wave crests in a lake are 5.0 m apart and pass by an anchored boat every 2.0 s. What is the speed of the water waves
