Bob
loves to garden and wants to grow lots of pink flowers for his friend
Sandy. He bought a special fertilizer to see if it will help plants
produce more flowers. He plants 10 plants of the same size in separate
containers with the same amount of potting soil. Five of the plants he
places in a sunny window and waters them every day with the same batch
of fertilized water. The other five plants are placed on a shelf in his
room and are watered with plain water every other day.What is wrong with Bob’s experiment? ExplainWhile
watching TV the other night, Jenny saw a commercial advertising Super
Green Brain Snacks, which were being sold as food to boost a person’s
learning power. As a student interested in being a biology major in
college, Jenny decides to do her own experiment to test whether the
information in the commercial is true. Jenny recruits five of her
friends and devises a test for them to take prior to eating any of the
Brain Snacks. Then, she has each of her friends eat one snack with each
of 3 meals each day for 3 weeks. At the end of the three weeks she gives
each of her friends the same test again. The results are as follows: TEST RESULTS Student Test Results Before (%) Test Results After (%) A 64% 80% B 78% 78% C 82% 84% D 69% 67% E 72% 70% Based on the data, do the Super Green Brain Snacks work? What is missing from Jenny’s experiment?

Rasmussen College Electricity Magnetism and Light Case Study
CompetencyConnect the principles of electricity, magnetism, and light to modern applications of physics.InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. Explain how these principals connect to electricity, magnetism, or light in modern applications in physics. Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. For instance, Maxwell's research led to the development of radio waves. If you listen to a radio, then you are using Maxwell's research. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below.ScenarioMandy took a trip to Rome, Italy. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. She found a charging station with a USB adaptor port. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone's screen told her the phone was successfully charging. This USB port seemed to have very high amperage, meaning it charged her phone quickly. She was aware, though, that almost all of Italy's electricity was generated by burning fossil fuels, and thus she was determined after this to use the portable solar charger she had bought rather than wall electricity.
