The force of attraction between a divalent cation and an divalent anion is 1. 67 × 10−8 n. If the ionic radius of the cation is 0. 080 nm, what is the anion radius?.

heat the gas and measure the pressure

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

it's a b and

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
