The variables for this experiment include mass, volume, and the materials in the various balls, as well as their densities. In Part I, you will be comparing a table tennis ball and a golf ball. Use the drop-down menus to complete the sentences and identify the independent and dependent variables. In Part I, the independent variable, the one that is intentionally manipulated, is . In Part I, the dependent variable, the one that you measure the response in, is .

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

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?
