Factors Affecting The Resistance Of Wire Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens

Romance of Resistance: Tracing Transformations of Power Through Bedouin Women‚” Lila Abu-Lughod discusses the growing resistance of Bedouin women of the Libya-Egypt region to the power dynamic embedded in their culture (Abu-Lughod 41 – 42). From her work in this region‚ Abu-Lughod hopes that through the discovery of the attempts of women to overcome the male to female power dynamic in this region‚ humans can better understand power through oppression. Once the relationship between resistance to the structure

modified? Detection of changes in blood pressure (leading to resultant changes in blood vessel diameter): Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. Afferents from the carotid region form
