Drinking cranberry juice is a fairly well-known and natural way to both help prevent urinary tract infections, as well as help speed the recovery process when a UTI develops. Just drinking two 4-ounce glasses of cranberry juice daily is often enough to both prevent a UTI and speed recovery when an infection does develop.
Ultrasound waves travel faster through a stiff medium, such as bone. In echocardiography, the velocity of sound is assumed to be approximately 1,540 m/sec (or 1.54 m/msec). Sound waves travel through the air with speed of 330 m/s.
The speed of sound is the rate of travel of a sound wave through an elastic medium. In dry air at 20 Â°C (68 Â°F), the speed of sound is 343 meters per second (1,125 ft/s). Thâ¦is equates to 1,236 kilometers per hour (768 mph), or about one kilometer in three seconds and about one mile in five seconds.
