Which vestibular nucleus projects to spinal cord to maintain posture?

Which statement best distinguishes Type I from Type II spiral ganglion neurons?

Supported scaffolds with a height greater than four times the base width must be ________________. 29 CFR 1926 Part 451(c)(1)

Scaffold platforms must be fully  ________________. 29 CFR 1926 Part 451(b) through 451(b)(1)

Two large lead spheres are sitting in a lab. Their masses are 56 kg and 39 kg. If the gravitational force between them is 9.4 x 10-8 N, what is the distance between the centers of these two large lead spheres? Show your work or explain your reasoning.

You are using a spring scale to measure the mass of objects hung from it. The spring’s equilibrium length is 11.0 cm. When you hang a 24 kg mass from the spring, it stretches the spring to 15.5 cm. What is the value of the spring constant? Show your work or explain your reasoning.

A plastic disk is spun on an axle through its center by an electric motor, going from 0 to 1700 rpm in 7.0 s. What is the angular acceleration of the disk during this time? Show your work or explain your reasoning.

A nut needs to be tightened with a wrench.   Which force shown will apply the greatest torque to the nut? [parta] Which force shown will apply zero torque to the nut? [partb] Give a brief explanation of your reasoning for each part.

A 275 g book is initially pushed to the right across a table with a speed of 1.3 m/s. Friction exerts a 0.37 N force on the book, slowing it down. Draw a force diagram for this situation with forces labeled. In the next questions, you’ll be asked to solve for the book’s acceleration and how far it will travel.  In this situation, the net force points toward the [parta]. On your paper, draw a force diagram of the book as it is sliding across the table and label all forces appropriately.   

Reference back to the previous question where a typical 3.5 inch diameter hard disk in a computer spins at a constant 6700 rpm. What is the centripetal acceleration that this speck of dust experiences? Show your work or explain your reasoning.
