Selma made an error while creating a chart to describe the technological design process for a new vacuum. Which best describes how Selma can correct the error in her chart? Change “Identify a need” to “Identify a problem.” Switch the descriptions for “Identify a need” and “Evaluate the solution.” Change “Implement the solution” to “Test the prototype.” Switch the stages “Evaluate the solution” and “Design a solution.”

Explanation:

switch the stages evaluate the solution and design a solution

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
