A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers
Answer:
v= 449.8 m/s
Explanation:
Given data
Frequency= 346Hz
Wave length= 1.4m
The expression below is used to find the speed

substitute

Hence the speed is v= 449.8 m/s
The unit of electric current is the 'ampere'.
That's the current in the circuit when one coulomb of charge
flows past any fixed point every second.
Answer:
it is a constant value that does not depend on the observer
