Consider the differential dz = [2xy + sin(y)]dx + [x^2 + xcos(y)]dy the state of the system is changed from (x = 0, y = 0) to (x = l ,y = 1) along the path x = y. calculate the total change in z along this path. the change in a.) is now made along the path x = y^2. compute the total change in z along this path. argue from your results and a.) and b.) and show explicitly that dz is an exact differential.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
