A particle exhibiting SHM moves along the x-axis in accordance with thedisplacement x=5cos(4 pi t+ pi 3 )cm What is (i) amplitude of motion? (ii) period of motion (iii) frequency of motion? (iv) time for x = 0

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

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?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.
