Select a manual lifting task in your workplace or another work environment. Then, follow the steps below using the NIOSH Lifting Equation (NIOSH, 1994). 1. Describe the manual lifting task.

2. Get the measurements of all the task variables for the task. Those are: (H, V, F, D, A, and C).

3. Obtain the values of the multipliers (HM, VM, FM, DM, AM, and CM) using the task variables (H, V, F, D, A, and C). Each multiplier can be found in the table or can be computed using the appropriate formula.

4. Obtain the Recommended Weight Limit (RWL)

5. Obtain the Lifting Index (LI).

The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0

Aspectroscope breaks light up into its colors, allowing scientists to analyze light from the solar system and universe. by studying the spectral line patterns, widths, strengths and positions, scientists can determine the speed, position, and of celestial bodies. a) age b) origin c) rotation d) temperature
