Value Units Submit Request AnswerPart A A sinusoidal wave has period 0.25 s and wavelength 2.0 m . What is the wave speed? Express your answer in meters per second. VO AEd O ? U= m/s Submit Request AnswerHome professionals like realtors use ultrasonic measuring tools to quickly measure the size of rooms. These instruments work by sending out a pulse of ultrasonic sound. then measuring the time it takes for this pulse to reflect off a wall and return to the device. Part A If you used such a device on a particularly hot day. would you measure the length of a given room to be longer or shorter than on a cool day? Construct the correct explanation. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. to be same a: a longer time than to be longer than Increase! with temperature \"sound """ T Increase! with temperature \"sound "" T the same time an decreases with temperature 1 \"soundN F does not depend on temperature to be shorter than a shorter time then decreases with temperature 1 l?"

Thus. the length of the room on a hot day will be measured 1:] on a c: What is the frequency of blue light that has a wavelength of 444 nm? Express your answer in hertz.
