What is the mass and speed of a particles related to its kinitic energy and temputre

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

Who was the first scientist to measure speed as distance over time?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
