Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.2589 n when separated by 50 cm, center-to-center. the spheres are then connected by a thin conducting wire. when the wire is removed, the spheres repel each other with an electrostatic force of 0.3456 n. what were the initial charges on the spheres? since one is negative and you cannot tell which is positive or negative, there are two solutions. take the absolute value of the charges and enter the smaller value here. enter the larger value here.

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

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 !
