A police car uses a radar gun to measure the velocity of a car and find out if it is speeding. The most common radar gun mounted inside the squad car window or dashboard and lies in the X band frequencies of microwaves of 10.50-10.55 GHz. A handheld version of this radar gun utilizes the K band frequencies between 24.05-24.25 GHz. A handheld radar (source of waves) with a frequency of 24.13 GHz is directed to car moving at 61...

Name: Doppler ultrasound PROBLEM 4-8 points Ultrasound is the name we give to sound waves that have a higher frequency than 20 kHz, which is the maximum frequency our ears can respond to. For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). 2 points] (a) Ultrasound equipment for diagnostic imaging typically uses frequencies between 1...

5. A student is asked to find the rate constant for a first-order reaction, given that (Alo = 10 M and after 20 s the concentration of A is 2.5 M. The student uses the following logic:2 rate = k[A] (for a first-order reaction) So: A[A] – k[A] Δt' Inserting the values gives: (2.5 M - 10 M - 205-05") = k[2.5 M] Solving for k gives 0.15 5-1. a.
