if they were matrices, they could be written as a function of A, which is the original matrix, the question said to write in terms of a, so I assumed it meant the determinant. Isn't that the case? If it isn't, please explain.
I'm giving a scholarship exam to study undergrad engineering in Japan. They have a sample test on their site for practice, I've attempted it but have no one to check my answers and they aren't given anywhere, so please check and correct whever nessasary

part 1 of problem one is definitely speed=distance/time, but the radius isn't the total distance travelled. try to figure out a way to find the total distance traveled in 1 whole revolution round the sun.
for part 2, you can use the equations of pseudo forces for circular motion.
I weigh 200 pounds today on earth, now I go Into an Isolated System (Say, an artificial Satellite) for six months, I eat healthy foods, drink a lot of water and regularly exercize (due to lack of anything else to do :D), so I'll lose weight, and hence mass.
1) Will there be any change in the...
Air and gasoline are mixtures, air is a mixture of oxygen, nitrogen and other gases in trace quantities, gasoline is a mixture of Octane and other hydrocarbons.
as for the conversion, I think you'll get 0.126 as the answer. to do it yourself , you have the conversion factor 1cm=10mm, cube both...
The electric flux, by a definiton, is the number of electric field lines per unit area. Yet, when we apply gauss' law for a 1 Coulumb charge, we get a non-integral value. What then, is the physical Significance of the value we get?
The whole concept is this. The electrostatic force is a force that acts from a distance, its magnitude inversely propotional to the square of the distance between the charges and directly propotional to the product of their charges. Now, as the force acts from a distance, there must be a way for...
The equation you gave can be converted to the osmosis equation for associating/dissociating solutes by multiplying the RHS with a factor 'i' (Also Called the Van't Hoff Factor)
So it becomes
Pi=iMRT
i is a factor defined as the number of particles after association/dissocation divided by the...
for determining hybridization, take into account the total electron pairs around the central atom, they maybe bond pairs, or lone pairs, the number of electron pairs is equal to the total number of hybridized orbitals (using pauli's exclusion principle, an orbital can't have more than 2...
AFAIK, there's no polar equivalent to adding numbers, so If anyone who knows how to solve it using polar system, please let us know.
Apart from that, it most prolly is to find the roots using quadratic formula in cartesian form ( x+iy ) and convert it to polar form
r(e)^iD, where...
