heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each gas. The apparatus consisted of a Kundt ’s tube‚ an osilliscope‚ a ruler‚ an audio oscillator‚ and a frequency counter. The experimental values of heat capacity were found to agree with the theoretical values within the range of uncertainty. This experiment

The fundamental premise underlying RFM analysis is that customers who have purchased recently‚ have made more purchases and have made larger purchases are more likely to respond to your offering than other customers who have purchased less recently‚ less often and in smaller amounts

Ultrasound instruments which are also known as sonographic instruments operate by using high frequency sound waves. These sound waves operate using a frequency range of 1 to 18 megahertz that can be used for imaging. These high-frequency sound waves are out of range of human hearing. The lower frequency of the sound waves produce less resolution but can produce images deeper into the human body. Higher frequency sound waves are capable of reflecting or scattering from smaller structures but are limited

This system operating at certain frequency can remotely detect the breathing and heartbeat signals of human beings buried under earthquake rubble. By proper processing of these signals‚ the status of the person under trap can be easily judged. The entire process takes
