The label has been scratched off a tuning fork and you need to know its frequency. From its size, you suspect that it is somewhere around 250 Hz. You find a 250-Hz tuning fork and a 270-Hz tuning fork. When you strike the 250-Hz fork and the fork of unknown frequency, a beat frequency of 5 Hz is produced. When you strike the unknown with the 270-Hz fork, the beat frequency is 15 Hz. What is the unknown frequency? Select...

and 4 and filling out the table
Lab 12. Sound Waves and Beats Introduction Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal. Using a Microphone and an interface, you can explore the properties of common sounds. The first property you will measure is the period, or the time for...

3. Remote Access: Suppose you have a computer with Internet connection at home. Files with sensitive information are stored on that computer and you often read and retrieve those files remotely. For security reason, describe one technology that you can use to access that computer and ensure the data transmission is encrypted. What is the name of the technology? What is the server port number? What is the encrypting method or algorithm used in that technology? Answer it within 10lines....

Start the Sound (uses Java) simulation (opens in a new window). Select the Measure" tab at the top left corner of your simulation window. Set the frequency to 200 Hz (once you click on the frequency button you can use the left and right arrow keys on your keyboard to decrease/increase the frequency to the desired value). Also set the amplitude to maximum. The waves are very now well defined. Pause the simulation. There are two blue lines that you...
