Will give Brainliest and Thanks! (Worth 30 points!) Make an Electromagnetic Spectrum journal with three entries.
(Be sure to include the type of Electromagnetic Spectrum, a picture of something that uses Electromagnetic Spectrum, and a brief description explaining how the thing uses the Electromagnetic Spectrum.)

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

Arrange the images in order to show how lake-effect snow occurs.
