Question

(II) check the correction of relation V = [E/ρ]1/2Where:- V = velocity of sound E = Co-efficient of elasticity ρ= density of medium. ​

Answer 1

Answer:

A galvanometer carries as maximum current of 15 mA, when a voltage of 75 mV is applied to it. How to convert this into a voltmeter to read upto 150 volt and into an ammeter to read upto 25 A

Answer 2

Explanation:

V = [E/ρ]1/2

Where:-

• V = velocity of sound
• E = Co-efficient of elasticity
• ρ = density of medium.
