Can you please answer all of demonstration 3,4,and 5

Thank you

For Demonstrations 3-5, you will be considering the motion of a mass (actually the same cart) suspended vertically from a spring, You can observe this motion by clicking here to download and View the Video. Demonstration 3: Suppose that increase the amplitude of the oscillation by pulling down the cart further below equilibrium before releasing it. Predict what effect this will have on the period and frequency of the motion. Only after you have made your prediction, click here to download a Video and View the motion and a graph? You can also click here to View just the graph. Did increasing the amplitude of the oscillation affect the period and frequency? If yes, describe the change. Demonstration 4: Suppose that increase the spring constant by suspending the cart with two springs next to each other. Predict what effect this will have on the period and frequency of the motion. Only after you have made your prediction, click [Lre to download a Video and View the motion and a graph? You can also click w to View just the graph. Did increasing the spring constant affect the period and frequency? If yes, describe the change. Demonstration 5: Suppose that increase the mass by hanging some weights from the bottom of the cart. Predict what effect this will have on the period and frequency of the motion. Only after you have made your prediction, click here to download a Video and View the motion and a graph.
