hin a free demo session as I have my answers, but just want to confirm them, that would be greatly appreciated. Question 1: A block of mass M = 0.10 kg is attached to one end of a spring with spring constant k = 100 N/m . The other end of the spring is attached to a fixed wall. The block is pushed against the spring, compressing it a distance x = 0.04 m . The block is then released from rest, and the block-spring system travels along a horizontal, rough track. Data collected from a motion detector are used to create a graph of the kinetic energy K and spring potential energy Us of the system as a function of the block's position as the spring expands. How can the student determine the amount of mechanical energy dissipated by friction as the spring expanded to its natural spring length? Question 2: The Atwood’s machine shown consists of two blocks connected by a light string that passes over a pulley of negligible mass and negligible friction. The blocks are released from rest, and m2 is greater than m1. Assume that the reference line of zero gravitational potential energy is the floor. Which of the following best represents the total gravitational potential energy U and total kinetic energy K of the block-block-Earth system as a function of the height h of block m1? Question 3: A 2 kg block is placed at the top of an incline and released from rest near Earth’s surface and unknown distance H above the ground. The angle θ between the ground and the incline is also unknown. Frictional forces between the block and the incline are considered to be negligible. The block eventually slides to the bottom of the incline after 0.75 s. The block’s velocity v as a function of time t is shown in the graph starting from the instant it is released. How could a student use the graph to determine the total energy of the block-Earth system? Question 4: A block slides across a flat, horizontal surface to the right. For each choice, the arrows represent velocity vectors of the block at successive intervals of time. Which of the following diagrams represents the situation in which the block loses kinetic energy?

I have two questions for you. I’m not sure how you paid for Walmart and CVS last year. When I made copies of receipts. I found out that you swapped the check 1234 \$200.00 from Walmart to CVS. I just entered the amounts from Paid Receipts Report on form A For Form B, I don’t see any box for 1-HP. Is it okay to add total form 1-ST and 1-HP together? Please let me know what your thoughts are. Thank you for your help.” " James, how come you ate lunch late? Eating late lunch is not good for you. Tell me what your favorite food is and i will treat you lunch one day after COVID is over" “ Are you eating Korean food? You make me feel hungry. I love to eat beef tongues and chicken bbq. I wish I could sit next to you. ” “ Thank you for sharing the information. You are the best teacher in the world.”

ing several continuous variables. The groups are in the same sample and the subjects can overlap. Some of the continuous/scale variables are moderated/lower correlated or not correlated with each other. Questions 1- Should I use ANOVA or MANOVA or some other method? 2- Is it okay to create a composed variable with all the combinations of the 3 groups using syntax? I excluded two of the combinations because they have only 1 or 0 subjects. I’m sending one example output in SPSS with one-way ANOVA and MANOVA.
