I'll paraphrase the question: There is a pallet with tomato cases on it and it is being lifted by a crane. Find the center of gravity in the horizontal plane so that the crane operator can pick up the load without tipping it.

What does it mean by "find the center of gravity in the horizontal plane"? Does it mean just find the Xcm? Or do I have to consider Ycm and Zcm as well?

Does the weight or mass of an object affect the timing of a free fall without reaching terminal velocity? If no, why not? If yes, why?
Does an object thrown down from a building with a force of 1000N go faster than an object that is released from the same height? Why?
Can you people try to help explain some concepts relating to my questions please?

So, to all you NASA-types in-the-know out there, here's a question for you - my husband and I got into an argument tonight about why they don't just send nuclear waste (which is, he argues, very expensive to hold here on Earth), on a suicidal spaceship into the sun? I responded with my general "Well, if they could do that, they would have by now" routine (too much faith in humanity, I know) but I theorized that the COST of a sort of "kamikaze" spaceship required to carry a load of nuclear waste to the sun would outweigh the expense of housing the waste here on Earth. Are we both way off here? Are there environmental concerns, or other reasons we haven't considered, that we don't just ship our dangerous garbage up to be consumed by the sun's constant explosions? What are we missing? Prove us both equally wrong and you may save a marriage... ;-)

What are the 3 Hardy Weinberg rules?
I'm not talking about the 5 things that would have to be in order for a population to be in equilibrium like: random mating, large population, no mutations, no migrations, and no natural selection. I'm talking about 3 rules.Thank you for your help.

No, the green flash is not a comic book super hero, but the last moment of light as the sun sets on a smooth horizon such as the ocean. Refraction and absorption cause the setting sun's last instant before setting to flash with a beautiful emerald green. What were the conditions and setting where you saw it? Was it as beautiful as I've heard.

We have been removing the oil from the earth for more than a century now. With less oil left in the ground to lubricate the axis as the earth spins around it wouldn't this create a lot of friction heat that might be the cause of global warming? Couldn't this also cause volcano's.
