Two identical charges, each -8.00 e-5 c, are separated by a distance of 20.0 cm (100 cm = 1 m). what is the force of repulsion? coulomb's constant is 9.00 e9 n*m2/c2 remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of significant digits to receive full credit.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
