## Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1884 edition. Excerpt: ...existing between the pressure, temperature, and density of a given gas. How is it proved that when a gas expands its temperature is diminished? (1, 1880.) 6. Sound is said to travel about four times as fast in water as in air. How has this been proved? State your reasons for thinking whether sound travels faster or slower in oil than in water. (1, 1881.) 7. A tuning fork is set in vibration and you hear its note. The sound is conveyed to your ear by the motion of the air particles in the room. Explain how, and in what direction, the particles move, and state how their motion would be modified if the fork were made to give a louder sound. (1,1882.) 8. Explain in what way the velocity of sound in water has been experimentally determined. (3, 1884.) 9. A tube, 1000 feet long, is filled with oxygen gas. Find how quickly the sound of a pistol shot will travel from one end of the tube to the other, it being given that the density of oxygen is 16 times as great as that of hydrogen, and that the velocity of sound in hydrogen is 4200 feet per second. (2, 1884.) B, --"Transmission of condensations and rarefactions. Formation of nodes and ventral segments. Vibration of strings. Reflection of waves. Longitudinal and transverse vibrations." 1. A musical string vibrates 400 times in a second: state what occurs when you shorten or lengthen the string without altering its tension, and also what occurs when you increase or lessen its tension without altering its length. (2, 1874.) 2. Beginning with a fundamental note of 256 vibrations a second, you are required to state the number of vibrations corresponding to the fourth, fifth, and octave of that note. (3, 1878.) 3. Explain the relation between the length of a rod of a given material, and the...show more
