An electron initially traveling at a speed of 10^5 m/s enters a region where there is a uniform magnetic field of 2 T oriented 45 degrees to its initial velocity. Quantitatively describe the trajectory of the electron, including its path, the orbi
Two identical 25 g particles each carry 2.0 uC (micro Coulomb's) of charge. One is held fixed, and the other is placed 1.0 mm away and released. A). Find the speed of the moving charge when it's 1.0 cm from the fixed charge.
Ascorbic acid (vitamin C) is a diprotic acid having the formula H2C6H6O6. Asample of a vitamin supplement was analyzed by titrating a 0.1500 gsample dissolved in water with 0.0240 M NaOH.

Aspirin is a monoprotic acid; its formula isHC9H7O4. Acertain pain reliever was analyzed for aspirin by dissolving 0.250 g of it in water and titrating it with0.0300 M KOH solution. The titration required 29.40 mL of base.
Two point charges, +2.0 uC (micro Coulomb's) and -4.0 uC (micro Coulomb's), lie 0.45 m apart on the x-axis. Are there any points on the x-axis where the electric potential is zero? If so, find the point(s). If not, explain.
An element is diamagnetic if it has no unpaired electrons. Anelement is paramagnetic if it has unpaired electrons. If sulfur has unpaired electrons in the last p orbital (1s22s2 2p6 3s2 3p4), why is it diamagnetic instead of paramagnetic?
