Define the use of quartz crystal method to detect ultrasonic waves.
Quartz crystal method:
This method is based onto the principle of Piezo-electric effect. While one pair of the opposite faces of a quartz crystal is representation to the ultrasonic waves, other pairs of opposite faces expanded opposite charges. Such charges are amplified and detected by using an electronic circuit.
Instantaneous velocity and speed are explained at a given or particular instant and are shown by ,
D=(a÷Sqrt(h**k**l**))
how to take readings from screw gauge and zero error of it
Explain Friction Force (Ffrict) Force exerted by a surface as an object moves across it or makes an effort to move across it. There are 2 parts of friction force - sliding and
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
suppose you are running and want to stop at once. surely you will have to produce negative acceleration in your speed. can you tell from where does the necessary force come ?
First Law: It shows that the mass (m) of substance deposited at the cathode during electrolysis is directly proportional to the quantity of electricity (total charge q) passed by t
write bernoulli,s equation using pressure,energy,and heads.
a column of water contains fine metal particles of radius 2*E(-8) m, which are in thermal equillibrium at 298 K. if there are 1000 particles per unit volume at a given height,how m
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
