Answer: vacuum
Explanation: The vacuum is the medium from where the sound wave cannot pass. A vacuum is basically an area without any air. Since the sound wave is a mechanical wave that's why it cannot travel through a medium where there is no matter of vibrations to works in, i.e, it can't travel through a vacuum.
Answer:
3 volts
Explanation:
Number of turns in primary coil =
= 100
Number of turns in secondary coil =
= 200
Voltage across primary coil =
= 1.5 volts
Voltage across secondary coil =
= ?
In a transformer, the ratio of number of turns of primary to secondary coil is equal to the ratio of the respective voltages i.e.

Using the given values, we get:

Thus, the voltage measure across secondary coil would be 3 volts
