Projectile motion problem, given the KE at the top of the parabolic arc
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.- Bilal Rajab Abbasi

Undergrad Introduction to Quantum Mechanics
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- Bilal Rajab Abbasi

Correct statement about internal energy
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...- Bilal Rajab Abbasi

Exploring Time Travel Possibilities in YA Fiction
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..- Bilal Rajab Abbasi

Equilibrium height of an air parcel
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...- Bilal Rajab Abbasi

Equilibrium height of an air parcel
@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...- Bilal Rajab Abbasi
