The position of a particle along a straight-line path is defined by s=(t3−6t2−15t+7) ft, where t is in seconds. part a part complete determine the total distance traveled when t = 11 s . express your answer to three significant figures and include the appropriate units. st = 640 ft previous answers correct part b what are the particle's average velocity at the time given in part a? express your answer to three significant figures and include the appropriate units.

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?

Based on the concept of the wave-like nature of light, huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. a) deflection b) interference c) refraction d) resonance

The two required components for a generator are
