A wire whose mass per unit length is 10^-3 kg/m is stretched by a load of 4kg over the two bridge os sonometer 1m apart. if it is struck at its middle point, what will be a. wavelength of its subsequent fundamental vibration b. the fundamental frequency of the note emitted if the wire struck at the point near one bridge what further frequency might be heard? ( assume g= 10m/s^2​

see earlier answer

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
