ound out about this website and I think I like it. I'm in the UK so I don't know if things are different there in america

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?

of the free trial. If you could please tell me when you're available. I just need a brief explanation

sted and I can see any changes in realtime. What I need is to take the duration in cells A2:A1000 and factor the dollar value in corresponding cells B2:B1000 in a way that causes the average amount earned per hour to calculate in cell D2. I'd appreciate a bit of help here, and I;d prefer if you could just plug the formula directly into cell D2 using the link below. The link to the editable document is: https://docs.google.com/spreadsheets/d/1lEJIPiSZJk9LYUTSA4oeDwyLXCVd18Zdewm6gnjxcXo/edit?usp=sharing Thanks!

oking for an online math and SAT/ACT tutor, possibly an IB Math tutor as well.  My children are native English speakers, but go to an international school. They are looking to attend an English speaking school for the university.  Can you please let me know the price range I am expected to pay per hour? Also, I haven’t had some of the best experiences in the past with someone claiming that they could help with SAT only to find out that they weren’t qualified. At this point, I will need a way to demonstrate your expertise as an SAT or ACT tutor. Also, for IB Math, if you are able to do both.  I look forward to hearing from you. Just to let you know, I have other friends looking for a similar tutor. Please make sure to send your CV, and a personal statement if you have one, so I can better understand your teaching/tutoring philosophy better.  Oh yes, where are you located for time zone differences?  Best, Edward Rochman
