Explain the basic concept of sonar.
Basic concept of SONAR:
Sonar is based ontpo the echo-sounding technique of ultrasound. While an ultrasonic wave is transmitted by water, this is reflected through the objects into the water and will generate an echo signal. By considering the time interval among the generation of the ultrasonic pulse and the reception of the echo signal (t), the depth of the object can be simply computed. As the ultrasonic velocity “v’ into sea water is termed, the depth of sea is computed as given below:
Depth of sea (distance in between surface and bottom of the sea) = vt/2
Similar procedure is also used to determine the distance of submarine or iceberg through the surface of the sea and the distance in between two ships into the sea.
This depends on the arrangement of a beam or column. for a simply supported beam with a point load in the centre of the beam Mmax = WL/4 and will occur at centre span W is the lo
what are the various types of tops ?
A simple inclined plane Join a spring balance to a toy car or roller skate and pull it up a slanting board (inclined plane). Note the force needed to move the car and compare i
Force: Force may be defined as a push or a pull upon an object. In the English system the pound (1b) is used to express the value of a force. For example, we say that a force
1. There are 40 such microwave hops in tandem. What is the end-to-end C/N of the link? 2. Assume now that these 40 hops are replaced by a single satellite hop as shown below.
Fig- detremines a square loop Made from a uniform wire. Determine the magnetic field at the centre of the square if a battery is connected among the points A and C.
Suppose you sound a 1056-Hz tuning fork at the same time you strike a note on the piano and hear 2 beats/second. You tighten the piano string very slightly and now hear 3 beats/s
what is capillary laws
A simple electric circuit, where current is represented by the letter i. The relationship among the voltage (V), resistance (R), and current (I) is V=IR; this is called as Ohm''s L
