A ship sonar detects an echo 1.6s after it sends the pluse. The speed of sound in water in 1500mls work out how deep the water is

1200m

Explanation:

Let the depth of sea be x.

Given that the sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.

Time taken to hear an echo t=1.6 s

Therefore, 2x = vt

Hence, we have 2x =1500m/s × 1.6s

=> 2x = 2400

⟹ x = 2400 ÷ 2

= 1200m

Hence, the final answer is 1200m

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
