**Problem: Sonar Frequency in Submarines**Two submarines are underwater and approaching each other head-on. Sub A has a speed of 12.6 m/s and Sub B has a speed of 8.99 m/s. Sub A sends out a 1530-Hz sonar wave that travels at a speed of 1522 m/s.(a) What is the frequency detected by Sub B? (b) Part of the sonar wave is reflected from B and returns to A. What frequency does A detect for this reflected wave?**Inputs for calculation:**(a) Number: [Input box] Units: [Dropdown menu](b) Number: [Input box] Units: [Dropdown menu]

Hassan is driving his truck with a velocity of 18m/s towards a mountain. Kevin who is riding in the truck sounds a horn. The sound reflects from the cliff and is heard by Hassan and Kevin on the truck. What is the change in frequency in hertz if the horn had an initial wavelength of )=0.101 m? The temperature that day was 35 degrees celsius. (Speed of sound = 331+0.6 T(in celsius)). Please give your answer as a whole number.

A) At this intensity, what is the average power incident on a pupil of diameter 8.20 mm in W B) If this light is produced by an isotropic source 15.5 m away, what is the average power emitted by the source? in W
Dolphins of the open ocean are classified as Type II Odontocetes (toothed whales). These animals use ultrasonic "clicks" with a frequency of about 55 kHz to navigate and find prey. Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 90 m below. How much time elapses before the dolphin hears the echoes of the clicks? (The speed of sound in seawater is approximately 1530 m/s.) What is the wavelength of 55 kHz sound in the ocean?
