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)

Asample of a gaseous substance changes into liquid. this process is called (blank) and it takes place when heat is (blank) a gaseous system

What is the angular momentum of the bar about the axle?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
