Answer 1

Answer:

$\huge\underbrace\mathfrak\pink{Answer}$

• An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can hear).

Answer 2

Total distance travelled by the ultrasonic waves=velocity of the ultrasonic waves* Total time taken by the ultrasonic waves

Therefore,

2*Depth of the sea=1400m/s*1.6s

Depth of sea=1120m
