Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.07 times a second. A tack is stuck in the tire at a distance of 0.335 m from the rotation axis. Noting that for every rotation the tack travels one circumference, find the tack's tangential speed.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

The ph is the a.independent variable b.the dependent variable c.control group

Select the best definition for wavelength. the height of an oscillating electromagnetic wave the rate at which electromagnetic waves oscillate. the distance between two crests of an electromagnetic wave. the oscillations of electric and magnetic fields select the best definition for frequency. the oscillations of electric and magnetic fields. the height of an oscillating electromagnetic wave. the distance between two crests of an electromagnetic wave. the rate at which electromagnetic waves oscillate
