In Concept Simulation 10.3 you can explore the concepts that are important in this problem. A block of mass m = 0.786 kg is fastened to an unstrained horizontal spring whose spring constant is k = 96.0 N/m. The block is given a displacement of +0.116 m, where the + sign indicates that the displacement is along the +x axis, and then released from rest. (a) What is the force (with sign) that the spring exerts on the block just before the block is released? (b) Find the angular frequency $\omega$ of the resulting oscillatory motion. (c) What is the maximum speed of the block? (d) Determine the magnitude of the maximum acceleration of the block.
2) A remote control car runs along a straight track and a student records the following data Time in s Position in m 0 10.00 1 16.16 2 17.33 3 14.50 4 8.67 5 0.833 6 -8.00 7 -16.83 8 ? a) Find the equation that describes this motion and the expected position at 8 s. (All the constants in your equation will be whole numbers in this case.)
Which of the following variables was NOT influential in the Rosenthal and Jacobson (1968) study? Group of answer choices more challenging material more feedback warmer classroom environment more parent-teacher contact
2. Our salt-precipitated protein (purple, red, or blue) will be re-dissolved in buffer that contains riboflavin (yellow) and passed over a desalting column. Which color should come off the column first; the protein pigments or the yellow riboflavin? Why? (1 pt)
If abnormal behavior is defined as behavior that causes personal discomfort, then all of the following people would need treatment EXCEPT Randy steals whenever he gets the chance. He's stolen family members' credit cards and he has even opened credit cards in other peoples' names. He says that they were stupid for not protecting their personal data. Marty feels nervous most of the day. He worries about everything and he also has anxious dreams. Sunam cries uncontrollably and spends nearly all of her time in bed. She has dropped out of school and says that she feels lonely. Barney fears interacting with people so much that he keeps to himself most of the time. He avoids going to the store for food because he feels as though people are watching him and judging him.
Let R be the region in the plane bounded between the curves y=x^2, y=0, x=0, and x=1. Find the volume of the object obtained by rotating R around the axis x=-1 using the method of cylindrical shells.
