Ahorizontal beam of light of intensity 25 w/m2 is sent through two polarizing sheets. the polarizing direction of the first makes a 15° angle with that of the second. suppose that the initial beam is unpolarized. what then is the intensity of the transmitted light? a. 7.2 w/m2 b. 11.7 w/m2 c. 12.1 w/m2 d. 23.3 w/m e. 24.1 w/m

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant

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.
