A rope is attached to the clapper of the bell. The bell is silent. In terms of energy, what causes the bell to ring?Immersive Reader Energy can be transferred from the rope to the clapper, and from the clapper to the bell, to make the bell vibrate. A vibration creates a sound.

Energy can be transferred from the rope to vibrate the bell. A vibration creates a sound to be transferred to the ears.

Energy from the rope can transfer vibrations from the air to the ears. This creates a sound.

Energy can be transferred from the rope to the bell and from the bell to the clapper. This vibrates the clapper and creates a sound.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
