A student hits a hockey puck with a hockey stick and the puck speeds up. Another student claims that the student broke the Law of Conservation of Momentum
because the puck gained momentum. Which of the following is the best
explanation of why the Law is not broken in this closed system?
The Law of Conservation of Momentum only applies for objects of equal mass.
The momentum of the puck is the same before and after the hockey stick hits
the puck.
The hockey stick loses as much momentum as the puck gained.
The force on the puck cancels the force on the hockey stick because the forces
are equal and opposite.

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
