The relationship between speed, frequency and wavelength of a wave is:

where v is the speed,

the wavelength and f the frequency.

In our problem, the frequency of the middle d note is f=293.66 Hz, while the speed of the wave (which is a sound wave) is v=343.06 m/s. Using the previous relationship, we can find the wavelength:

Converting into centimeters, we have:

<u>The fraction of the total kinetic energy that is rotational for a uniform sphere is</u><u>** 1/3.**</u>

<h3>What is kinetic energy?</h3>

**Kinetic energy** is a form of energy that an object or a particle has by reason of its motion.- If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Option (a)

Option (b) uniform sphere

C) uniform hollow sphere

D) uniform hollow cylinder with inner radius R/2 and outer radius R

that fraction of total energy as rotational energy is given as

A) uniform Solid cylinder for cylinder we know that

= 0.5

B) uniform Sphere for sphere we know that

C) uniform hollow sphere for hollow sphere we know that

D) uniform hollow cylinder with inner radius R/2 and outer radius R for annular cylinder
