Two balls are on a frictionless horizontal tabletop. ball x initially moves at 10 meters per second, as shown in figure 1 above. it then collides elastically with identical ball y which is initially at rest. after the collision, ball x moves at 6 meters per second along a path at 53 degrees to its original direction, as shown in figure 2 above, which of the following diagrams best represents the motion of ball y after the collision?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
