A student bends a paper clip back and forth rapidly. After repeating this action several times, the student touches the bent part of the paper clip and observes that the metal has become warm. Which statement best explains the student's observation? Because mass is lost from the paper clip, heat energy is increased in the paper clip. Because volume is lost from the paper clip, heat energy is increased in the paper clip. Because energy is conserved, some energy of motion is converted into heat in the paper clip. Because energy is conserved, some of the motion is converted into electricity in the paper clip.​

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?
