true of false, Answer with supporting evidence pleaseWhen metals are subject to a tensile stress, the strain is alwaysproportional the magnitude of the stress.when materials are subjected to a compressive stress, the youngsmodulus is always positive
1. Is there any difference between the static charges generated by rubbing rods with fur or silk and the charges that flow (from a battery) through wires in an electric circuit? Give evidence for your answer.
2. For the circuit on the right, indicate whether the statements below are TRUE or FALSE. If a statement is TRUE, briefly describe the evidence from this lab that supports this statement. If a statement is FALSE, give a correct statement, and briefly describe the evidence from this lab that supports this new statement.
a. The current flows from the battery, through wire A, through the bulb, and then back to the battery through wire B
b. Since the current is used up by the bulb, the current in wire B is smaller than the current in wire A
c. The current flows toward the bulb in both wires A and B
d. If wire B is disconnected, but wire A is left connected, the bulb will still light, but if wire A is disconnected and wire B is left connected, the bulb will not light.
e. A current sensor will read the same magnitude if connected to measure the current in wire A, and then connected to measure the current in wire B.
3. Name the circuit element represented by each of the following symbols:
Please answer all short answer questions!1. What value does the image distance approach as the object distance becomes larger?2. What value does the object distance approach as the image distance becomes larger?3. What is the relationship between image distance and object distance? (Directly related or inversely related?) Give evidence supporting your answer.4. Where would you place the object to obtain an image as far away from the lens as possible?5. Where would you place the object to obtain an image located at the focal length of the lens ?6. Using your answer from above and your experiences in this activity, explain why ”fixed lens” cameras require that the subject of the photo be a minimum distance from the lens.
