What two things would need to happen for the hypothesis to eventually become a theory?

For a hypothesis to become a theory, it needs to be supported by numerous, well-designed experiments that consistently yield the same results. Additionally, the scientific community must widely accept the hypothesis as being a reliable explanation for the observed phenomena.


What two things occur for a collision to be effective?

For a collision to be effective, two things must occur: the collision must have enough energy to overcome any energy barriers in the reactants, and the reactant molecules must approach each other with the correct orientation to allow the necessary bonds to form.


What two things must the effort force applied to a machine do?

The effort force applied to a machine must overcome the resistance force to perform work, and it must transfer energy to the machine to allow it to do its intended task efficiently.
