please help solve all questions thanks

To satisfy the objectives of this experiment, follow the link below and do the following steps. https://phet.colorado.edu/sims/html/masses-and-springs/latest/masses-and-springs_en.html 1- Click on lab screen and use the mass ( 6 6: controller to control the mass hanged to the spring (m), set m =150kg. Pering Trace mass controller Spring constant controller Record the mass in table 2. 2- Control the spring constant using the spring constant controller and set it at Derrung the large value. 03:01.12 WICK 3- Click on time meter and drag it near the spring. Put V on period trace Time meter selection to trace the line of full cycle. 11 8mm 4- Compress the spring to the maximum Masses and Springs compression, Set the simulation PHET speed at slow mode. 5- Press on start Potton, watch the trace of full cycle, then press the arrowhead on timer meter to start measuring the periodic time (T). Record the periodic time in table 2. 6- Repeat the previous steps for different masses of (m) as shown in the table 2. Record your data in the table 2. Data Analysis: 1. Calculate the square of the periodic time (T2). . Use Excel sofware to plot a graph of T2 versus m, T2 as the ordinate and m as the abscissa. 3 . Use the equation of the graph to determine its slope, use the slope of the line to calculate the acceleration due to gravity g which is given by: k =_ 4 72 slope Table 2 m (kg) T(s) IT2 ( $2) Questions: 1- Explain what will happen to the periodic time? if you change the 50 spring constant to the low value. 100 140 180 220 260 300 Explain theoretically how can you determine the spring constant using hooks law
