A student has 500 identical, rectangular sheets of paper. The mass of of the paper is
0.080 kg
(a) Using a metre rule, she measures the length of one sheet of paper and its width. The length is
0.300 m and the width is 0.210 m.
(0) Calculate the mass of one sheet of paper.

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

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
