U.S. History
To what extent would it be accurate to say that New England, Middle, and Southern Colonies had merged to create a single American Society by the end of the French and Indian War?

physics
An electron is accelerated by a 4.7 kV potential difference. How strong a magnetic field must be experienced by the electron if its path is a circle of radius 8.0 cm?

physics
A 16.0 ohm and a 24.0 ohm resistor are connected in parallel. A difference in potential of 32.0 V is applied to the combination. What is the equivalent resistance of the parallel circuit? What is the total current in the circuit?

Physics
The nucleus of an atom has a charge of 65 protons. (a) What are the direction and magnitude of the electric field at 4.9 x 10^-10 m from the nucleus?

physics
d would be 1/4 * F qA and d would be 6 * F

physics
Two charges, qA and qB, are separated by a distance, d, and exert a force, F, on each other. Analyze Coulomb's law and answer the following questions. What new force will exist if d is cut in half? What new force will exist if qA is tripled and d is doubled?

physics
A positive charge of q = 2.6 µC is pulled on by two negative charges. As shown below, one, −2.0 µC, is 0.050 m to the north and the other, −4.0 µC, is d = 0.029 m to the south. What total force is exerted on the positive charge?
