if gravity is the bending of space through time(simply put) then if time stops, does gravity cease to exist?

this is the joke but i only get the separate vocabulary but not the funny part. explain because im not much of a big words person lol


Your mother is so dumb that she designed experiments exploiting quantum mechanics in an effort to determine the nonlocality inherant in the microcosmos and undermine the true nature of the uncertainty principle!

Einselection seems to explain the outcomes of distinct states and the onset of classical reality. Unfortunately, there are other anomalies to take into consideration. What quantum theory best explains these anomalies? I think the Consciousness Causes Collapse Theory is incredibly interesting but highly unlikely. What are your thoughts on this theory, and do you think it displays a valid answer to the random outcomes or anomalies?

on any of the species who do this?

If it (cannibalism) isn't practiced by all carnivores and omnivores, is there a reliable source where I can access a list of species who do practice it?

Thanks. ☺

You are designing a pendulum designed to wreck buildings called a "wrecking ball". When the ball is displaced from its equilibrium position by 30 degrees on a 20 meter line, you would like it to have energy equal to 35,000 Joules when it returns to its equilibrium position. What mass must the wrecking ball have to accomplish this?

A simple atwood's machine uses 2 masses m1 and m2. Starting from rest, the speed of the two masses is 5.2m/s at the end of 6.7s. At that time, the kinetic energy of the system is 77J and each mass has moved a distance of 17.42 m.

The acceleration of gravity is 9.8m/s2.

a.)Find the value of the heavier mass
b.)Find the value of the lighter mass

If you look towards the origin of The Big Bang then in theory you are looking back in time. So, if you turn 180 degrees, would you be looking into the future?

I have to take a Fortran(90) class next spring and I know a tiny bit of C++, will Fortran be easier or harder to learn than C++? Thanks.

I have been barely passing my math and physics classes. I'm talking B's and C's. I am thinking of majoring in electrical engineering. It's my third year, I have to declare my major soon. I'm wondering, will an average student like me make it as an engineer? I am not particularly passionate about this field, and I'm not un-passionate either. It's mostly the high salary that appeals to me because of the high cost of living. I want a stable job. I mean, I do ok during class it's just that I don't retain the information after class is over, and I think I'd be in big trouble if I have to recall this information for a job someday. Should I proceed in this direction? I feel like crying.

Red, then Green, now Blue....could one be made by collimating all those three colors, kind of like yellow lasers are made with red and green diodes?
Might there be some theoretical way to make a single white laser diode, kind of like the recent white LED breakthrough?

1)Calculate the normality of a solution that was prepared by dissolving 43.3 g of barium hydroxide in enough water to make 2160.0 mL of solution.

2)Balance the following equations:
MnO4- (aq) + H+ (aq) + Br- (aq) --> Mn2+ (aq) + Br2 (l) + H2O (l)

MnO4- (aq) + H2O (l) + NO2- (aq) --> MnO2 (s) + NO3- (aq) + OH- (aq)

3) Balance the following equation for a reaction in acidic solution. Only H+ or H2O may be added.
Cl2(g) --> ClO3-(aq) + Cl-(aq)

4)The following reaction occurs in basic solution. Balance it by adding only OH- or H2O.

N2H4(aq) + Cu(OH)2(s) --> N2(g)+ Cu(s)

5) Oxygen gas can be generated by heating KClO3 in the presence of some MnO2.
2KClO3 --> 2KCl + 3O2

If all the KClO3 in a mixture containing 2.07 g KClO3 and 0.30 g MnO2 is decomposed, how many liters of O2 gas will be generated at T = 28.0oC and P = 754.8 torr?

THANK YOU!!!!!

Rank the arrangements in the picture according to the magnitude of the electric field at the center of the curvature, largest first.

http://img62.imageshack.us/img62/7821/92127235fc2.png

The instructor says that all of them have the same electric potential because they all have the same distance R and the same charge Q. But then, for electric field, the magnitude would be similar, just with an R^2 on bottom instead of just R. That would mean that all four are the same for electric field as well, right?.

But it looks to me that if the charge was evenly distributed the electric field on 4 should be 0, since it is pushing evenly on P from all directions and everything would cancel. Is this because E is a vector and therefore depends on direction as well as magnitude, while V only depends on magnitude? Or am I just not thinking straight and am totally off?

So how do you rank them?
