Which statement best explains how tectonic activity affects long-term climate change? Volcanic eruptions can cause both global warming and global cooling.
The movement of continents changes wind patterns and ocean currents.
The change in Earth’s tilt and its orbit around the Sun cause climate change.
The increase of sunspots increases Earth’s temperature.

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.
