I'm in a thing call TEAMS Engineering. Basically there's 8 people on a team and we get 1 hour 30 mins to answer questions about 10 college level engineering problems (each w/ several questions) (we're are in high school). We're allowed to bring in any texts/info we want but it's so hard 50% is...

I have a test on Monday. I am still having trouble with the following concepts. ***Please remember I am just taking the physical science kind of physics.*** Q. For the astronauts inside the orbiting space shuttle, there is no force of Earth's gravity acting on them. True or false? A. Answer...

How am I supposed to figure out these concepts? No problems to do, but I'm just not understanding the material/concepts? anyone care to explain/teach me? 5.) Weight of a man who is throwing a bag of potatoes? 7/8) Net acceleration of a body on a curved path 10) Kinetic energy of a...

Hello , it's me again. It's about proving linear aalgebra concepts. 1. Show that if A = A^-1, then det (A) = 1 or -1. 2. Show that if A^T = A^-1, then det (A) = 1 or -1.

In the contemplation of values we must distinguish between that which is value in our being and that which HAS value. I ask - what is the difference? ---------------------------------- The difference by my theory is: Value can never be static; meaning that experience adds to...

[SOLVED] 2 concepts of Time Travel My concepts are based on Logic (not on physics nor mathmatics); Note: Sorry for my spelling. I don't use English much. 1. The balloon Theroy Ones needs to always look at the universe as a connections of mass elements. All elements follow a straight...

p and q are real numbers. If p < q then [p,q] = {x : p <= x <= q} or (p,q] = {x : p < x <= q} or [p,q) = {x : p <= x < q} or (p,q) = {x : p < x < q} . A single-simultaneous-connection is any single real number included in p,q ( = D = Discreteness = a localized...

Hi, To check a bijection between two sets, we have to look at the contents of the two examined sets as if they are discrete elements, otherwise we can't use the bijection method. |R| = Continuum, so my question is, how can we check if there is or there is not a bijection between |Q|...

Confused w/ some physics concepts! I don't know anything about guitars,...can someone please explain to me what is the different bet a acoustical guitar and an electric guitar (their amps, frequency...)? How amp play a role in an electric guitar?

Often times, the religiously drowned population, as well as just non-science people with honest intentions, like to use the word "theory" against a scientific concept. Let's face it, outside of the scientific community people know not a thing about science. To be widely considered a theory in...

What is so important about plank length i.e. why are seemingly unrelated things such as curled up dimensions and superstrings plank length?
