Poor girls are not interested in school (is a false statement) as: firstly: there were no proper school facilities and not expert teachers who attended school on a regular basis. Secondly:parents preferred van services which were not available frequently. Thirdly: parents wanted girls to help them with household work and preferred sending boys to school instead of girls.

Write a short note on Sonar

Posted by Krish Krish 6 years ago

CBSE > Class 07 > Science

1 answers

.. ... 6 years ago

Sonar (sound navigation and ranging) it is a device that uses ultrasonic waves to measure distance,direction and speed of underwater objects. The transmitter produces and transmit ultrasonic waves.These waves travel through water and after striking the objects on seabed,get reflected back and are sensed by the detector.The detector converts ultrasonic waves into electrical signals which are interpreted. The time taken for the echo to return to ship is measured by sonar apparatus.The distance of underwater object is then calculated from time taken by echo to return.The time it takes for an echo to return is used to find out how far away something is. 2d=v*t d=distance from ship to the bed of the sea v=speed of sound through seawater t=time interval between transmission and reception of ultrasound signal.
