Answer:
option (a)
Explanation:
To make a galvanometer into voltmeter, we have to connect a high resistance in series combination.
The voltmeter is connected in parallel combination with teh resistor to find the voltage drop across it.
An ideal voltmeter has very high resistance that means it has a resistance as infinity.
Do you mean when objects move as a direct result of the passing wave?
Waves have energy and constitute a force, just like wind. Therefore that
force is able to move objects in its path.
