Tera performed multiple experiments to determine the best growing conditions for azaleas. in one experiment, she tested the effect of using different types of soil. in another experiment, she tested the effect of exposing the plants to varying amounts of light. and, in another experiment, she tested the use of different amounts of fertilizer. once she completed her experiments, tera recorded all of her observations before making a conclusion.
this scenario suggests that
a. scientific hypotheses should be made after reaching a conclusion.
b.
scientific explanations are based on evidence, or data.
c.
scientific questions are often solved by performing a single experiment.
d.
scientific evidence includes observations, data, and personal opinions.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

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.
