What's three pieces of evidence that Wegener used to support his theory ( Alfred Wegener’s hypothesis of continental drift states that the continents once formed a single landmass, broke up, and drifted to their present locations ) and why it is important to have several pieces of evidence when proposing a theory to describe phenomena like Alfred Wegener did.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
