How does convection cause tectonic plates to move? A
Convection keeps the plates thin enough to move.

B
Convection makes the plates solid enough to move.

C
The rising heat of convection currents moves the almost-liquid rocks.

D
The pressure of convection bends rocks until they break completely.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

The two required components for a generator are

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.)
