It is generally a good idea to gain an understanding of the "size" of units. Consider the objects listed and calculate the magnitude of their momentum in SI units. A ladybug weighing 31.80 mg flies by your head at 2.53 mi/h.

Which of the following correctly describes the early view of catastrophism?

Avalue that describes how heavy an object is and is related to the force of gravity is

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
