Acoin with a 2-cm diameter is dropped onto a sheet of paper ruled by parallel lines that are 3 cm apart. which is more likely, that the coin will land on a line, or that it will not?

How do you tell if someone actually cares about you? and just say they do?

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.

How do cracks affect the rate of weathering?
