David is experimenting with electromagnetic waves. He has four different waves to study, wave A, wave B, wave C, and wave D. In wave A, distance between two corresponding points on adjacent waves is greater than that of wave B. In wave C, the number of waves that pass a fixed point in a given time is greater than that of wave D. Which wave has higher frequency, wave C or wave D?
Ans: wave C

The 2 team took different approaches in reinforcing the highway embankment slopes when building segments of the interstate. Team A led by Chuck relied almost entirely on inspiration and good building materials, while team B lead by Mike used nature as an ally by planting hundreds of thousand of trees and shrubs to prevent slope failures. Which team contributed to increasing the chances of slope failure?
Ans: Team A

When studying the kinetic-molecular theory, two teams of students did and experiment. Team A heated a can of soup over the fire without venting it first, team B heated a can of soup, but vented it first. Which team observed more kinetic energy causing the air molecules to move faster?
Ans: Team A
