Which form of energy converts sedimentary rocks into metamorphic rocks in the rock cycle? a. thermal b. kinetic c. solar d. electrical

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
