354795 Assertion :
A tuning fork is made of an alloy of steel, nickel and chromium.
Reason :
The alloy of steel, nickel and chromium is called elinvar.

354796 Assertion :
Two arms of a tuning fork vibrate in different phase.
Reason :
Both arms in a tuning fork have same frequency of vibration.

354797 A source emitting sound of frequency \(100\;Hz\) is placed in front of a wall at a distance of \(2\;m\) from it. A detector is also placed in front of the wall at the same distance from it. The minimum distance between the source and the detector for which detector detects a maximum of sound is
\(\left( {{v_{sound{\rm{ }}}} = 360\;m/s} \right)\)

354798 Assertion :
Soldiers are asked to break steps while crossing the bridge.
Reason :
The frequency of marching may be equal to the natural frequency of bridge and may lead to resonance which can break the bridge.
