We want to construct a thermometer using mercuyr. as the mercury in the bulb is heated, it expands and moves up the thin capillary tube connected to the bulb. the symbol used for the coefficient of of volume expansion of a substance due to ta temperature increase is b(sigma). it is used in the following equation: deltav = bv(deltat)

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

The ability to make things happen is also called a. heat b. force c. matter d. energy

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?
