1) If vector A = 5i +7j -3k , vector B =2i +2j -ck r perpendicular to each other find the value of c?
2)Two vectors start from origin and end at (1,3,4)and(1,2,3).whats their cross product?
3)A vector Fa is along positive X-axis.If it s vector product with Fb is zero than Fb is what??? Answer in unit vectors
4) what will bethe angle between vectors -2i +3j+k and -i +2j +2k
5)Three vectors A,B and C satisfy the relation A.B=0 , A.C=0 than vector A will be parallel what????

If time slows down according to e=mc^2 (Twin Paradox) then you could, in theory, travel so fast that time could be relatively 0 (or very close to it). If rt=d and the rate of speed is whatever that rate is and the time is 0 or very close to it, the distance traveled would be 0 or very close to it. So, there is a point at which it doesn't do any good to travel any faster b/c the distance traveled would be less.

A four digit No: when divided by 10 the remainder would be 9, and the same four digit no: when divided by 9 the remainder would be 8, again the same four digit no: when divided by 8, the remainder would be 7, and so on until when divided by 2, the remainder would be 1 ? What is that four digit no:

How will Planet Earth be viewed once human beings colonize another planet?

Who will be left behind?

Will it become a wasteland, or something else unforeseen?

I know this may sound like a stupid question, but I was wondering how we all came to be of different ethnicities. For instance, they say man came to be from the big bang theory and then from homosapiens, and from a religious point of view we came to be from God when he made Adam and Eve( thought I wish he would have made Adam and Eve, Amanda and Evelyn, and Andre and Ethan). Anyway, I was wondering how we all came to be of different skin colors?

I've always pondered this. Can the fact that when one sleeps be equated to time traveling into the future?

If you were to observe someone in a deep state of sleep, would you not think that at that moment of observing them, they are actually awake at a given time in the future?

What I am saying is that, for the observer, looking at the person who is asleep, their time has already fast-fowarded into the future, while, you as an observer, is traveling through time.

Please ask for more details if I am not making myself clear enough.
