Can we upload a picture of solution here?

Thanks. I had corrected that and solved it.

Future Physicist to re-arrange the Theory of Everything.

Can I get a solution on that please I have my sendups coming and this question is part of the syllabus It's an important one.

0.5 * mv^2sinx=0.25*(1/2 mv^2cosx) Cosx/sinx=4 after cutting the common values Tanx=sinx/cosx Tanx=1/4 X=14.1 That was my attempt In order to get the answer right I did this (tan inverse of 4 minus tan inverse of -1/4 Answer is 61 degrees neglecting negative angle But actually its 60.

Thanks

Um, see The explanation at the end please

Hi! I am Bilal Rajab. I have a question regarding Quantum Physics. From where can we learn about Quantum Physics and what is its relation to Classical Physics? Why is there not one single Physics...? Thanks Regards, Bilal Rajab Abbasi

No D is probably not the answer..because friction "does" involve transfer of heat energy itself. C: As temperature is the average Kinetic Energy of all the particles in the body.. your first equation denies this fact. As you are adding P.E to K.E to get U B: Yes. When the temperature of a body...

You might want to see some of the lectures of Stephen Hawking.

Use the concept of Black Holes... You can make him enter a black hole and time will pass very very slow there relative to earth... Make distance of Days longer in that planet... Time will pass slowly, then..

For example; You can simplify Γ(a)=-M(a)g/C(a) and Γ(b)=-M(a)gT(b)/C(b)T(a) And z''=g((M(a)T(b)/M(b)T(a))-1) this equation by using Linear Algebra... Replace the symbol M with "x" and z with Y i.e, y"=g((x(a)T(b)... If you are using differentiation to find the answer then it is very simple...

@Rahan amin Make simultaneous equations and solve. Find the variable you were asking about. Mass always is a constant wheras Weight varies with height. A variable here would specifically be the temperature of the test substances you are using. Also equate the equations like make two equations...
