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.
What are simple ways to quantify the dryness of a semi-permeable hard surface?
1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
a transformer has a primary coil with 200 turns, and a secondary coil with 2000 turns. The input voltage is 120 VAC, and runs at 1800 watts. What is the output voltage?
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
