Task 1 (3 points) A bent bar lies in a vertical plane, the x-y plane, and is affected in addition to the attachment by two forces Poch 3P, and a moment M1 = 2P · a.P = 1kN, a = 0.5m and  b= 30 °. Decide in vector form: a) the force resultant b) the […]

Using components determine the sum of a  +  b   if  a  = 3 m [N 30° W] and  b  = 2 m [N 10° E]. Note: Since the use of components is a useful strategy for word problems later in this course, your solution must make use of vector components.         So […]

Related Diversification. Related Diversification is the most popular distinction between the different types of diversification and is made with regard to how close the field of diversification is to the field of the existing business activities. Related Diversification occurs when a company adds to or expands its existing line of production or markets. For this […]

Calculate the efficiency number and write up the results report. Include photos, explanation of what you saw, process steps, discussion of the results, and any other information you feel will explain your choice of beam design and your reaction to its performance.         So much stress and so little time? We’ve got […]

Write a two-page paper double space that answers the following questions. Any graphs or data that are included does not count towards the required two pages. 12pt font should be used with a one-inch maximum margin. This lab is about CAT/PET Scans. Describe the physics as to how each machine operates! How are they different? […]

1. Using Equation 4.4, show that d represents the mean distance neutrons travel before being absorbed.25. If you were located 100 km from a 1 GW nuclear power plant, what would the neutrino flux be at your location? Assume that a 1 GW nuclear power plant releases 1021 neutrinos per second and you present a […]

a gas sample is heated from 20 to 57 A gas sample is heated from -20.0 Degree C to 57.0 Degree C and the volume is increased from 2.00 L to 4.50 L. If the initial pressure is 0.134 atm, what is the final pressure? 0.0457 atm -0.170 atm 0.393 atm 0.231 atm 0.0777 atm […]

A 760-µF capacitor is connected in series to a 150 V power supply and a 1.5 k? resistor. At t = 800 ms, the switch is flipped such that the capacitor is in series with only the 175-mH inductor.  At the moment the switch is flipped, what is the voltage (potential) across the capacitor? How much charge is on the capacitor? After the switch is flipped, what is the frequency of oscillation? What is the maximum current in the circuit? What is the maximum energy stored in the magnetic field of the inductor?

Pick a source of energy (wind, solar, hydro, coal, natural gas, hydrogen, petroleum, nuclear, fusion, wave, tidal, etc.) and write two pages about it. You should include the following: – brief overview of the science behind turning this resource into usable energy – climate or other environmental impact of this energy source – current usage (how prevalent is this energy source in the US? the world?) You can of course include more than that, but I at least want to see that info. Format: 12 pt font, 1″ margins, single spaced, maximum two pictures (no more than 3.5″ on a side)
