I need help answering question 1-1 and 1-2

INVESTIGATION 1: MEASURING FORCES In this investigation you will explore the concept of a constant force and n combination of forces in one dimension You can use these concepts to lean how to measure forces with a force probe, You will need the following materials. computer-based laboratory system motion software RealTime Physics Mechanics experiment configuration files Wireless force probe five identical rubber bands #16 (E- spring scale with a maximum reading of 5 N smooth track 2.2 m long with safety stop, block and lab jack spring FICIASIO Activity 1-1: How Large Is a Pull? If you pull on a rubber band attached at one end, you know it will stretch. The more you pull, the more it stretches. Try it. Place a lab jack and block at each end of the table and place the 2.2 m track on them. Attach the safety stop to the track to be used as a fixed point. 1. Slide the rubber band around the loose end of the safety stop and position it so that it is close and parallel to the centimeter scale when stretched. Now stretch the rubber band so it is ten centimeters longer than its relaxed length. We will call this the "standard length". Does it always seem to exert the same pull on you each time it is stretched to the same length? (Most people agree that this is obvious.) yld Answer: do ne lo ne bar 2. Attach one end of each of two identical rubber bands to the safety stop and stretch them together side-by-side to the same standard length. 3. Repeat this with three, four, and five rubber bands stretched together to the same standard length. del Question 1-1: How does the combined force of two or more rubber bands compare to what you felt when only one rubber band was used? Question 1-2: Suppose you stretched a rubber band to your standard length by pulling on it. Now you want to create a force six times as large. How could you create such a force?
