Present Your Findings
Write a summary paragraph discussing this experiment and the results. Use the following questions to help guide the content of your paragraph.
Submit your recorded observations for each step.
Step 1: Burning Candle - record the mass and write your observations
Step 2: Cooling Candle - record the mass and write your observations
Step 3: Tearing paper - record your observations
Step 4: Wet paper - record your observations
Step 5: Burning pieces of paper - record your observations
Step 6: Salt and water in test tube - record your observations
Step 7: Baking soda and vinegar - record your observations
Answer the following questions.
What is the difference between a physical change and a chemical change?
What kind of change occurred in each test? What evidence do you have to support your decision?
Be brief, but be sure to defend your conclusion with data.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
