The diagram shows ned’s movement as he left his house and traveled to different places throughout the day. which reference point should be used to find out how far ned traveled when he went from the pet store to the swimming pool?

Protons and neutrons are found within the nucleus of an atom

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

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?
