- The angle of what is equal to the angle between the normal and incoming waveEqual loudness curves represent the results of measurements of A absolute threshold. B perceived magnitude. C single cell recordings. D neuroimaging procedures.3) If it takes 0.87-s to hear a gun-shot 300-m away, what is the speed of sound at that location? V=
- 20. What would the speed of an observer be if a red (4.688 x 1014 Hz) traffic light appeared green (5.555 × 1014 Hz) to the observer? A) 4.445 x 10$ m/s B) 2.219 × 10$ m/s C) 8.438 × 107 m/s D) 5.548 x 107 m/s E) 2.890 × 10 m/s Ans: DA yoyo of radius R and mass M is released from rest with the string vertical and its top end fixed up a support as shown below. How fast is the center of mass of the yoyo moving when it has fallen a distance of 47 cm. Ignore the mass of the string and express your answer if m/sBecause of the Doppler effect, the sound heard by an observer listening to a moving ambulance siren, compared to what the observer would have heard if the observer and siren were both at rest... will have a lower pitch if the ambulance siren is moving towards the observer. will have a longer wavelength if the ambulance siren is moving towards the observer. will have a lower frequency if the ambulance siren is moving towards the observer will have a higher frequency if the ambulance siren is moving away from the observer. will have a higher frequency if the ambulance siren is moving towards the observer.
- I did A-C, provided them below. Not sure how to do D and E#77A police officer's radar gun emits radio waves at a frequency of 11.9 GHz. What is the difference in the frequencies reflected back to the radar gun by a car traveling at the 45 mph speed limit and a car travelling 1 mph faster? Assume that the cars are both headed directly away from the stationary officer. 35.54 difference between frequencies: Hz Incorrect
- Doppler effect question: a police officer is not moving and uses a machine to measure the speed of a car approaching. The machine emits a sound wave with a frequency of 24333 Hz. The sound wave travels towards the car, and is reflected then comes back to the police officer. When it comes back, the machine then mesure the waves at a frequency of 27745 Hz. The sound speed is 334 m/s. In km/h, what is the speed of the car?Wien’s displacement law holds good only for shorter wavelength. a) False b) TrueA student with a VO2max of 55 ml/kg/min runs exactly 2 miles in 16 minutes. This intensity represents what % of his VO2max? Round the final answer to the nearest whole percent.
