I'm looking for a way to rotate blocks. There is a single axle going through the blocks.. say there are a dozen of them. I am trying to figure out a way to rotate each block individually to one of the 4 sides based on different inputs. I am also trying to accomplish this with a single motor...
Homework Statement
A particle moves with constant speed in a circle with a radius of 5m in a counter-clockwise direction. It makes 1 revolution every 16 seconds.
What is the average velocity for 1/4 revolution? 5/4 revolutions?
Homework Equations
Wrapping Function: W = (cos t, sin t)...
Homework Statement
Find the derivative of the function f(x) = sqrt(x).
(Bear in mind that cannot use the power rule or anything like it. I must use limh->0.)
Homework Equations
limh->0 (f(x+h) - f(x))/h
The Attempt at a Solution
I'm getting hung up on expanding out the...
Homework Statement
Find the range of h
Homework Equations
h(x) = sqrt(25 + (x - 3)2)
The Attempt at a Solution
I factored out the (x-3)2 and simplified to get
sqrt(x2 - 6x + 34)
I was trying to figure out the domain first, knowing that x2 - 6x >= -34 in order for the...
This is the one occupation that I'm sure I would love, but the more I read on it, the more impossible it seems that I will land a tenured university position.
I'm a 1st year student at Michigan State and have a 3.9 at the moment. I imagine I'll end up in the 3.75+ area after my physics...
..sucks. I have the Sky-Watcher 10" dob (got it for xmas). All around, it's a great scope for the cost, and produces some very crisp visuals of surprisingly distant objects... when it can center on them. I find myself having to constantly aim higher than the object so my telescope will "fall"...
Which fields of engineering involve the most physics. I'm a physics major at the moment, but after seeing how ridiculous it is to land a tenure position at a university, I'm considering switching to engineering. What do you guys suggest for a physics/math buff?
Up until middle school.. math was my thing. I wouldn't say I "enjoyed" it, but it definitely came naturally. My teacher even forced me to do math counts in 7th and 8th grade. We had a grad student as our coach and he always tried to get me into math, and, for whatever reason, I just really...
Is there a distance where the curvature in spacetime created by an object's mass ends? Is it a finite gravity well or does the curvature just get infinitely weaker?
A while back, I posted here asking for telescope recommendations. After many members advised getting a dob, http://www.skywatcherusa.com/8-dobsonian-telescope-s11700.html" [Broken] is what I went with.
I love this scope. Seems very well put together and can capture some pretty amazing...
I know the topic is incredibly original, but I was just curious as to how many people genuinely accept this as a feasible explanation for the creation of the universe. Personally.. I think (at least for a long time) that there is no way of knowing. I don't like how mainstream this theory has...
I'm a freshmen in college (currently undecided on my major) and am seriously considering an undergrad in physics with the intention of going to graduate school for astronomy. But before I get serious about it, and with Christmas on the way, I want to get a decent telescope. I'd say my possible...
