Draw a diagram that represents how a mechanical wave interacts with a particular material. i.
Choose a material that will interact with a mechanical wave.
ii.
Include reflection, absorption, and transmission in your diagram.
iii. Label your diagram "Mechanical Wave Interactions."
iv. Below the diagram, write a brief description of the interaction between the mechanical waves
and the material. Include an explanation of how the amplitude and frequency of the wave are
affected.

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
