What kind of line represents “a moment of time” on a spacetime diagram? A) Parabola, because it look like a bowl. B) Now doesn't exist for all observers so there is line that represents a moment in time! C) Lines that are parallel to the spatial/”x” axis. Lines that are parallel to the temporal/”ct” axis.

Question A3 a) With respect to the spacetime line element ds2, what distinguishes trajectories classified as time- like, null or spacelike? Which type of trajectory must a massive particle follow? b) Why do we need the covariant derivative? Write down the covariant derivative acting on a cov- ector field. What is the covariant derivative of the metric?

E.g. "What is space time fabric? Is it even a real thing or just an hypothetical concept to explain gravity?" Answer: Spacetime is real. The fabric part is a metaphor to help us understand the geometry better because you can't visualize spacetime. The way we perceive time isn't tied to spatial dimensions like length, width and height. But it is tied to those dimensions and we need a tool to use to visualize it. Typically we picture it as a...

question 7 and 8
Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...

Choose a symbol from either "The Gift of the Magi" and discuss what significance this symbol had to you as the reader (an example of this would be the combs Jim gave to Della and a discussion about a precious gift that you received or gave). Use text examples in this section. If someone were to write your life story, what symbol would be present and why? How does this symbol represent you? You can attach a picture of your symbol (an...

Summary task: C++ language; practice combining tools(functions, arrays, different kind of loops) to solve somewhat complex problem. Description A Valiant Hero is about to go on a quest to defeat a Vile Monster. However, the Hero is also quite clever and wants to be prepared for the battle ahead. For this question, you will write a program that will simulate the results of the upcoming battle so as to help the hero make the proper preparations. Part 1 First, you...
