A disk initially at rest is acted on by a constant net torque τ (think of this as force, F). The disk spins for a period of t seconds and rotates an angular distance of Δθ. The same disk is then brought to rest. The disk is now acted upon by a constant net torque 2τ (think of this as force, 2F). The disk spins for the same period of t seconds. What is the new angular distance the disk rotates?

Apropagating wave in space with electric and magnetic components. these components oscillate at right angles to each other. it may travel in a vacuum. determine the term.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?
