The final lesson in the 20-part series is a post assessment covering earthquakes and volcanoes. Twenty-three questions incorporate each of the previous lessons through multiple choice, justified multiple choice, expanded multiple choice,...

Practice using lossless text and image compression algorithms and considering what data can be compressed most easily.

Check your understanding of lossy and lossless compression techniques, in this set of free practice questions designed for AP Computer Science Principles students.

Determine the internal energy in a sample of gas that goes through an isothermal compression.

Determine the work that was done when no heat enters or leaves the system. A video describing the problem can be found here: https://www.youtube.com/watch?v=vt0u94PtbJ8&feature=youtu.be

Students must predict the distance traveled by a box that has been projected horizontally by a compressed spring. The box will start with potential energy due to elasticity and it will turn into KE without loss. It will then lose its...

Test yourself on the topics of identifying the characteristics of a longitudinal or transverse wave such as the wavelength, crest, and areas of compression with this multiple choice quiz.

Students must solve for the tension in the rope and the acceleration of the car based on the angle of displacement for a hanging mass.
