Constantan: Constantan is a copper-nickel alloy. The amount of nickel in constantan is 40%.
Properties:
1. It is silver like appearance.
2. Its electrical resistivity is 5.2*10-8 ohm-m.
3. Its SPECIFIC gravity is 8.9.
4. Its melts at 1300 degree c.
5. The maximum permissible working temperature is about 500 degree c.
6. It can be drawn into thin wires.
7. It is highly corrosion resistant.
USES: It is used for making resistance elements for items like loading rheostats and starters for electric motors. It is also used in thermocouples.
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 7.5 km/s and the secondary, or S, wave
to measure the extension of an experimental wire due to different pulling forces using searle''s apparatues.hence, determine the young modules of the material of the wire.
Can you explain about sharpness of resonance?
Hello! I would like to ask if there is a job in Physics which is 24/7 Question Answering/problem solving and if any, I would like to apply for it. Thank You Prerak Dhawan
