Sound travels when the molecules in the ( medium, ear drum, transmit, cochlea ) vibrates. The closer the molecules are, the ( faster, slower, more curved ) sound travels. The fastest medium is a ( solid, liquid, gas, vacuum ) while sound does not travel in a ( vacuum, solid, liquid, gas ). In the ear, a vibrating object e.g. a trumpet produces waves. Sound then travels from the ( medium, vacuum, air, ear ) (air) to the ear. The vibrating air enters the ear, fuelled to the ( ear canal, optic nerve, cochlea, ossicles, drum ). The vibrating air sets up vibrations in the ( ear drums, ear canal, auditory nerve, vacuum, cochlea ). The ear drums then transmit the vibrations to the small bones called ( ossicles, cochlea, ear canal, ear drums ), causing them to vibrate. The ( cochlea, ear drums, ossicles, vacuum, auditory nerve ) vibrates. These vibrations are detected by the hair lining and the ( auditory nerve, cochlea, ear drums, ossicles, ear canal ) will then detect these vibrations and send the impulses to the brain.

Question 10 of 10

1

Fill the blank spaces to complete the text.

An echo sounder ship is tested where the sea bed is known to be 60 m deep. The time between sending each ultrasonic pulse and receiving its echo was measured at 0.1s. The time for the ultrasonic wave to reach the sea bed is s. To find the speed, we have to use the equation speed = distance/time, so division by = m/s.
