Which of the following is an application of the doppler effect used by submarines? adar radio sonar scuba

SONAR

Explanation:

SONAR = Sound Navigation and Ranging

This technique is used to find the position of other ship or we can use this to find the depth of the sea.

In this method sound waves are projected from the ship and then it gets reflected back from the solid surface.

This reflected wave is again detected by the detector on the ship and time is measured to get the wave back

So the distance moved by the sound waves is given by

so here we can say that distance moved by the sound is product of speed and time

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
