- Assume that the board you used was covered with two materials, material 1 and material 2. If the height where the wooden block started to slide down is higher on material 2 than on material 1, what can we say about the μs and μk associated with material 2 as compared to material 1? a. μs and μk on material 2 is higher than on material 1b. μs and μk on material 1 is higher than on material 2c. μs on material 2 is higher than on material 1, but μk material 1 is higher than on material 2d. μs on material 1 is higher than on material 2, but μk material 2 is higher than on material 1e. Regarless of any height, μs and μk is same on material 1 and material 2b) translation: "Find a matrix S transpose which defines a shear parallel to L, with shear factor 1/2"Help with this homework question would be great, thanks!
- The question is whether these relationships are linear or non-linear, can you please inform me on how I'd be able to tell?can i please get help on this type of problem please. I would really apprecite it. i am having trouble with parts d-g. A muscle cell (fiber) in a biceps is 20cm long and contains 1500 myofibrils arranged parallel to each other. Each myofibril is made up of many sarcomeres, organized in series, that behave as springs. A relaxed sarcomere is 2μm long. When contracted, the cell shortens to half its length and develops a force of 30mN. Each of those structures, the cell, myofibril and sarcomere, can be modeled as a spring. a) Calculate the spring constant of a muscle cell. b) The 1500 myofibrils in the muscle cell are arranged in parallel. Calculate the spring constant of a single myofibril. c) The myofibrils are composed of sarcomeres that are arranged in series. Calculate the number of sarcomeres in each myofibril then calculate the spring constant of a single sarcomere. d) When we shiver in the cold, our muscles oscillate at a frequency of 10Hz and with an amplitude of 2cm. Assume…Part B isn't correct
- In part a, Why does your I go from from 4.54 x 10^-4 to 4.66 x 10^-4 in the final equation?Please help me with these problems. We are using algebra based physics, not calc basedi just have a question on the algebra on this portion of the problem, what happens to the negative sign that is factored out when you're trying to find the final velocity?
