In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.
Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.
In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.
Learners read definitions of the terminology associated with algebraic operations and then follow steps to use the fundamental laws of division to simplify algebraic expressions.
The TI-83 Plus Calculator: The Square Root Function
Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.
