If crank ab is rotating with an angular velocity of ωab = 6 rad/s , determine the velocity of the center o of the gear at the instant θ = 64 ∘.

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of
