Two particles, with identical positive charges and a separation of 2.85 x 10⁻² m, are released from rest. Immediately after the release, particle 1 has an acceleration vector a₁ whose magnitude is 4.50 x 10³ m/s², while particle 2 has an acceleration vector a₂ whose magnitude is 8.15 x 10³ m/s². Particle 1 has a mass of 6.40 10⁻⁶ kg.
Find
(a) the charge on each particle C and
(b) the mass of particle 2. kg

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?

As microwave light travels through a liquid, it moves at a speed of 2.2 x 108 m/s. if the frequency of this light wave is 1.1 x 108 hz, what is the wavelength of this microwave?
