=4.5kgandradiusr=8.5cmcan rotate about a fixed vertical axis on frictionless bearings. a massless, stretchless cord passes around the equator of the shell, over a pulley of rotational inertia i = 3.0 x 10‐3 kg m2 and radius r = 5.0 cm, and is attached to a small object of mass m = 0.60 kg, which hangs on the end of the cord. there is no friction on the pulley's axle; the cord does not slip on the pulley. what is the speed of the object when it has fallen 82 cm after being released from rest? use energy considerations.

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
