1. Create an essay or PowerPoint to analyze a technology or procedure that applies the principles of energy and momentum. Propose a practical way to improve the technology or procedure (or ways it has been improved] and assess its impact on society and the environment. Include pictures or diagrams (word limit of 750}. Be sure to reference all information sources and pictures. An example would be reworks. 2. Use the links that 1 provided and complete the following questions. Ensure to use graphs [and label them!) Once you have completed the data table, use Desmos to make a graph of Force vs SeparationDistance {r}. Make sure to title your graph and axes. Make a second graph of force vs using Desmos. Title your graphs and axes. Use the Force vs graph to nd the value of Coulomb Constant "it\". Then calculate the percentage error. Place two-point charges, with the same charges {both positive or both negative), in a horizontalor vertical straight line. Place a sensor along the same line. Take a screen shot and include it with this assignment. Using your measurements from the simulation, calculate the net Electric Field acting on the sensor. Include all your steps. How close are the two values (use percentage error to express this value). Repeat these steps but use difference charges (one positive and one negative}. Change the distance between the charges and the sensor. 3. Complete the following questions a. in Millikan's experiment, a drop of radius of 1.64pm and density 0.851 gem3 is suspendedin the lower chamber when a downward-pointing electric eld of 1.92 x 105 N] C is applied. i) What is the weight of the drop? ll} Find the charge on the drop, in terms of 2. iii] How many excess or decit electrons does it have? b. A proton is moved from the negative to the positive plate of a parallel-plate arrangement. The plates are 1.50 cm apart, and the electric eld is uniform with a magnitude of 1 500 MC. i) What is the proton's potential energy change? ii) What is the potential difference between the plates? ill) What Is the potential difference between the negative plate and a point midway betweenthe plates? mi) If the proton is released from rest at the positive plate, what speed will it have just beforeit hits the negative plate? c. An electron at rest is accelerated by a uniform electric eld [1 000 Wm} pointing vertimliyupward. Using Newton's laws, nd the electron's velocity after it moves 0.50 cm [includea direction] d. An electron gun shoots electrons at a metal plate that is 4.0 mm away in a vacuum. 1he plate ls 5.0 V lower in potential than the gun. How fast must the electrons be moving as they leave the gun if they are to reach the plate? e. An electron is moving the east with a speed of 5.0 x 10'i mls. There is an electric eld of 3.0 kam in the east direction. What will be the electrons speed after it has moved 1.00cm
