The word "Communism" has completely changed its original meaning, a once harmless idea to unite people and their goals is now used as a term for "Evil". The original thought of people working side by side and for their government has now warped and changed into a society where their higherups become greedy and would do anything to stay in power.

I can use a standard x-y coordinate system (that is perpendicular to the floor) for my calculations up until it reaches the ramp, and then use an x-y coordinate system that is perpendicular to the inclined surface, and it doesn't matter, right? As long as I'm consistent? I'm talking about using Work Energy Theorem/Non-Conservation/Conservation of Mechanical Energy to find the height up the ramp that the block travels.

Anybody read 1984? If i'm using "Class Structure" in a comparrison essay, which situation sounds better for a "reaction" to how the Proles are treated differently?

1. The higher classes are treated better (i.e. O'Brien)

2. Or the mention in Goldsteins book where "the low will rise and take over the high"

Can anyone give me a few examples of global encounter between 1500 and 1920

by global enconters, do you mean when one nation interacted with another in a certain way?

For mechanical oscillations, when you have the equation mu'' + (gamma)u' + ku = F(t), and they ask for the natural frequency, is it sqrt(k/m) or is it 1/(2pi) * sqrt(k/m)? I've seen it expressed in both ways throughout the internet.

Natural frequency is sqrt(k/m). 1/(2pi * sqrt(k/m)) is the period.

Speaking of which, my professor keeps telling me that I have to find k (we'll have something like 2u'' + 2u + ku = 2cos3t) and I have no idea how to find k considering I don't know natural frequency, I don't have an equilibrium state that will isolate it for me, and I need it to define my other equations

Didn't know that. I think I was getting a bit confused with my equations though because I would have a spring that has an original length, then adding a weight to it stretches it a certain length, and then we pull it a certain amount to start it bouncing. So I wasn't sure what "position" I'd have to consider as the coefficient to my k.

Hands of a clock suggest an angle whose measure is continually changing. How many degrees does a minute hand move through during each time interval?

A. 9 min B. 35 min C.45 min

D

54 degrees

207 degrees

271 degrees

these are all rounded the nearest degree

basically i just divided 60 by 9/35/45 respectively then divided 360 by the product of that

i'm not sure if this is what you wanted, tbh

And before you ask, I couldn't afford the books for the class so I couldn't get it. That and I'm the only one in that class from the town that I live in.

I think I'm getting there, but I'm still stuck. Like for A, I multiplied it by 60(for minutes) and got 540 but I'm not sure what to do after that.

EDIT: wait thats not what you said it all. doing it your way and I got 7 for A

D

gotta find what each minute on the clock is in degrees, which is as simple as dividing 360 by 60 then multiplying by the number of minutes needed

so

360/60 = 6

x = number of minutes

y = degrees

so 6x = y

so, i overcomplicated it a bit which gave a slight inaccuracy due to to rounding, this should work better for you

wait, I think that you need to find what degree each second is on the clock, which IS 360/60 you're right about that. i multiplied the amount of minutes by 60(seconds). so for A that would be 540, then you divide by the number of degrees per second which is 90.

so A would be 90. B would be 350, and C would be 450. Is that right?

if you cant find the actual story, sparknotes might be able to help you

you are saying that in 45 minutes the minute hand moves 450 degrees. so, incorrect, my friendwait, I think that you need to find what degree each second is on the clock, which IS 360/60 you're right about that. i multiplied the amount of minutes by 60(seconds). so for A that would be 540, then you divide by the number of degrees per second which is 90.

the minute hand moves 6 degrees per minute. that information should make the rest easy for you.
