An Algorithm for Converting a Hexadecimal Number to a Decimal Number
In this animated and interactive object, learners follow two methods for converting a hexadecimal number to a decimal number. They test their knowledge in exercises at the end of the learning object.
Financial Statements: What Are They? What Do They Mean?
Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.
Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.
Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
In this interactive object, learners examine terminology dealing with phonics and whole language and identify the different types of activities that would be seen in a phonics-based or whole language classroom. Part of this activity has audio.
Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
