Simplify as much as b and c are three points in the plane. where a, 2. let u and v two non-parallel nozero vectors. determine the real number a so that the vectors au + (1- a)v and (2 + a)u + av are parallel.

What is an aquifer for science class

If you held a stone over the mouth of a well and then let it go , what would happen to the stone? explain your answer.

2.which choice most accurately explains what happens to the bonds between atoms when water changes to steam, and what becomes of the energy added during this phase change? when water changes to steam bonds between molecules are created. after reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms. when water changes to steam bonds between molecules break apart. after reaching the boiling point, energy is used to break bonds, but does not affect the kinetic energy of the atoms. when water changes to steam bonds between molecules are created. after reaching the boiling point, energy is used to break bonds, but does not affect the kinetic energy of the atoms. when water changes to steam bonds between molecules break apart. after reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms.
