CApress your aliswei lu iwu siyiicaln nyures alnu iIGiuue uie approphate umLS. A motion sensor can accurately measure the distance d to an object repeatedly via the sonar technique. (Older autofocusing cameras determine the distance by emitting a pulse of very high frequency (ultrasonic) sound that travels to the object being photographed, and include a sensor that detects the returning reflected sound, as shown in the figure.) (Figure 1) A short ultrasonic pulse is emitted and reflects from any objects it encounters, creating echo pulses upon their arrival back at the sensor. The sensor measures the time interval t between ? dmax = Value Units Submit Request Answer the emission of the original pulse and the arrival of the first echo. Part C Figure 1 of 1 Assume that during a lab period the room's temperature increases from 20°C to 24 °C. What percent error will this introduce into the motion sensor's distance measurements?
