Do you know some soft. which could analyze light spectrum(.jpg)?

no I'm not

There is a base-quadrilateraled pyramid ABCDS , which base is quadrilateral ABCD. Inscribed sphere is tangent in point P on the ABCD wall. Proof that <)APB+<)CPD=180' I don't like geometry and i really don't know how to start.

no,no delete this i made an error

any comments?

ok so, I read that mechanical energy(E): E=-MmG/R R=(a+b)/2 a-semi-major axis b-semi-minor axis ,of course kinetical Ek=mv^2/2 m-spaceship weight Ep=-mMG/r v^2/2-MG/r=-2MG/(a+b) and a-sqrt(a^2-b^2)=<r=<a+sqrt(a^2-b^2) and v^2 for some r is less than 0 M>>m

F=p*S=ro*g*h=dv/dt*S*ro*h v=dh/dt

Can an airship rotate the Earth and the Earth is not in eliptical orbit's focus ?(can be in center?)

longest, thanks

What is the maximum wavelength of m101 seen from the Earth by eye?

(ax2+bx+c)(dx2+ex+f) ad=1 ae+bd=1 cf=52 bf+ce=0 be+af+dc=-14 c,a,d,f =/= 0

but i read that all pol. can be factored in reals and the higher power of x can be 2

x^4-14x^2+52 i don't know how to factorize it in reals.

ok, now i see your solution, thanks, big thanks

please, help me:)
