hin a free demo session as I have my answers, but just want to confirm them, that would be greatly appreciated.
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?
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?
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?
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?
https://opengeology.org/historicalgeology/virtual-field-experiences-vfes/vfe-glaciers/#Continental_glaciation_in_LiDAR And go/view liDAR image map of Scandinavia below the heading “Continental glaciation in liDAR” to view the image portion of the Scandanivia map on that site. I need help for this one final question regarding this liDAR image of Scandinavia for this lab assignment I’m doing to “Identify one of each of the following geomorphic 5 features below each associated with continental glaciation (TAKE a screenshot on your PC of an example of each from this liDAR map image of Scandinavia, and send those 5 images, labeling key features of the image, and put all 5 screenshot images of these below features with their labeled annotated key features in a Word Doc or PDF to SEND to me). From accessing this website link and using the liDAR map image of Scandinavia take take these 5 key feature screenshots, HERE are there 5 required features BELOW required to screenshot with key features labeled/annotated to take one of each on your PC( press “Fn” + “PrtScr” to screenshot images on your Windows PC(don’t know how on Mac PC) or use/downloa snippet program to take computer screenshots of these 5 features):
kettles SEE attached photo file for same directions for this question as typed here, but for more better simpler clarity to read the same directions as typed here on this attached file. ALSO THIS Assignment is really due by 11:59 pm tonight 11/7, but I want it done at least by 7 or 8 pm today 11/7. Thanks, please try to help me ASAP, I’m struggling.
