Speed of light

The speed at which the light travels in a vacuum is unbiased for both the source and inertial frame of reference of the observer. This was postulated by the physicist, Albert Einstein, by observing the theory of electromagnetism of Maxwell. Also, there was no evidence for the luminiferous aether, that is, the medium for the propagation of light where the electromagnetic field exists.

1. You and a friend set up an umbrella and chairs at Torrey Pines State Beach. Your friend goes boogie boarding while you read a book. Half an hour later you are surprised to see that your friend has moved south, parallel to the beach. They are still boogie boarding the same distance from shore, in the surf zone. Why did your friend drift parallel to the beach? 2. The Sun is much more massive than the Moon, but the Moon has a bigger influence on Earth's tides than the Sun. Why is this? 3. Even when there is no wind at the beach, we still see waves. What is the source of these waves? Do not include tides, mass movement, or earthquakes in your answer. 4. What causes ocean surface water to sink to the bottom and become deep water? Where does this happen? 5. How do you escape a Rip Current?
An astronaut in deep space is at rest relative to a nearby space station. The astronaut needs to return to the space station. A student makes the following claim: “The astronaut should position her feet pointing away from the space station. Then, she should repeatedly move her feet in the opposite direction to each other. This action will propel the astronaut toward the space station.” Is the student’s claim correct? Justify your selection. a Yes. The astronaut’s feet will have a velocity that is transferred to her center of mass, accelerating the astronaut toward the space station. b No. The astronaut would move away from the space station, not toward it, since her feet are pointed away from the space station. c Yes. The astronaut’s feet exert a force away from the space station, creating an equal and opposite force that will accelerate the astronaut toward the space station. d No. The astronaut’s feet are not exerting a force on another object, so…
