In M theory there are 11 dimensions. Besides the common three axis, time, and the eleventh that seems to tie it all together what are the other six dimensions?

(1)The avrg. speed of a runner in a 400 meter race is 8m/s. How long did it take the runner to complete the race?
I got 50s. Is that right?

(2)Which statement about the movement of an object with zero acceleration is true? The object must be at rest. Is that right?

(3) An object travels for 8 seconds with an avrg. speed of 160 m/s. The distance traveled by the object is ... 20m. Is that right?

That's all thank you so much for your time!!

While it is true that a larger apeture helps in collecting more light on a reflector to be able to see more of a planety or deep sky stuff.

However dosen't magnification help in dealienating the surface or other things on a planetry surface as opposed to apeture. So say if I wanted to see more details on saturn through my P130mm 650 focal would it make sense that things would be more detailed with higher mags as opposed to simply increasing the apeture. Atleast going by the rule of 50X per inch of apeture.

Are there any other ways besides barlows to see more planetry surface details by keeping the same apeture.

Thanks

P.S I am not overly concerend with the field of view which ofcourse relates inversely to mag what I seek is an ability to see details to the best to p130mm 650's ablities.

Does the shortest day always fall on the twenty-first, or can it be affected by leap years, I ask this question because I have a calendar that says it was the twenty-second, so I mentioned this in the local cafe and was pounced upon by everyone.

in any way is it possible?
ok if you mark a piece of paper with a maker....the paper is absorbing theparticles of the marker......when you put the marker in water..the water is obsorbing the marker particles like the solid(paper.....when you leave a marker without a top...the air absorbs the marker particle (causing it to dry out)....so does that mean you have accomplished writing on air, solid, and liquid

Ag + Cu(NO3)2 ---> ____________

the 3 and 2 are subscript numbers.

it's a single displacement reaction, and Ag has a charge of 1, NO3 has a charge of -1.

can you explain every single step, please, because i'm really confused.

Thanks!
