To Explain:The way placing hand on a bell that has just been rung stops the sound.
Explanation of Solution
Introduction:
Sound is a form of energy and is produced by vibrations in the molecules of the medium. The sound waves are mechanical waves and vibration is produced as the sound travels.
Sound produces sensation in the ear, and is produced by vibration. When the vibration stops, the object will stop producing sound. As such, when a hand is placed in the ringing bell, the vibrations in the bell will be stopped by the hand. Hence the sound will stop.
Conclusion:
Hence, by placing a hand in a ringing bell, the sound will stop.

- T1. Calculate what is the received frequency when the car drives away from the radar antenna at a speed v of a) 1 m/s ( = 3.6 km/h), b) 10 m/s ( = 36 km/h), c) 30 m /s ( = 108 km/h) . The radar transmission frequency f is 24.125 GHz = 24.125*10^9 Hz, about 24 GHz. Speed of light 2.998 *10^8 m/s.arrow_forwardNo Chatgpt please will upvotearrow_forwardNo Chatgpt please will upvotearrow_forward

A measurement taken from the UW Jacobson Observatory (Latitude: 47.660503°, Longitude: -122.309424°, Altitude: 220.00 feet) when its local sidereal time is 120.00° makes the following observations of a space object (Based on Curtis Problems 5.12 + 5.13): Azimuth: 225.00° Azimuth rate: 2.0000°/s. Elevation: 75.000° Elevation rate: -0.5000°/s Range: 1500.0 km Range rate: -1.0000 km/s a. What are the r & v vectors (the state vector) in geocentric coordinates? (Answer r = [-2503.47 v = [17.298 4885.2 5.920 5577.6] -2.663]) b. Calculate the orbital elements of the satellite. (For your thoughts: what type of object would this be?)
