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.
Q. A managing wire of length 2m has a diameter of 0.4 mm with a resistance of 70 ohm. Find its resistivity. ρ = ( P X πr 2 ) / L = ( 70 X 22 X 2 X 10 -4 X 2
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
