Suppose two point charges, Q1 = +3.37 x 10-6 C and Q2 = -8.21 x 10-6 C, are separated by a distance d = 1.99 m. Using Coulomb's Law, find the attractive force between the charges. A) F = 0.0626 N B) F = 0.0313 N C) F = -0.0626 N D) F = -0.0313 N
Ps If you could explain how you got it it would help a lot. Thank you so much.

Which feature indicates that mars resides in the inner region of the solar system

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form
