Step 1
To define a transverse wave in respect to the speed of sound, we need to understand that a transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. In this case, if the speed of sound is 320 Show more…

Pre-Lab Questions 1. Figure 1 is a sample paper chromatogram for three samples A, B, C. Label the drawing with the following items: the stationary phase, the mobile phase, and the solvent front. 2. Calculate the Rf value for the spot in sample B using sample A as an example. 3. Sample C gives two spots on the paper chromatogram. What does this tell you about the composition of the sample?

PRE-LABORATORY QUESTIONS Answer 1-4 1. Why do we need to consume food? 2. One serving of Cheetos® (1 oz = 28 grams) contains 10 grams of fat, 14 grams of carbs, and 2 grams of protein. Calculate the energy content per gram of Cheetos®. 3. In this experiment, the food sample you will use may not burn completely. Will this affect your result? 4. A 12-oz can of Coca-Cola® contains 39 grams of sugar and no fat or protein. How many food calories will a can of this soft drink provide?
