(HELP ASAP PLEASE) Imagine an object moving at a constant velocity. With respect to the magnitude and direction of the object’s velocity: 1. Describe what happens if a force acts on the object in a direction parallel to its velocity. 2. Describe what happens if a force acts on the object in a direction perpendicular to its velocity. 3. Explain the source, direction, and effect of the force acting on satellites in orbit around Earth.

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?
