Anna drives north at a speed of 50 km/h for the first hour. then, she drives north for a second hour but slows down to 30 km/h. compare or contrast the first hour of her trip to the second hour of her trip.

group of answer choices

the distance is greater in the first hour because her speed is faster.

the distance is greater in the second hour because her speed is slower.

the displacement is the same for both hours because she is travelling north the entire time.

the distances are the same for both hours because she is travelling north the entire time.

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?
