Ameterstick is balanced on a fulcrum at its center. then a 240 n weight is placed 15 cm to the left of center. how many cm to the right of center would a 200 n weight need to be placed in order to balance the system?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
