VRAAG 2 VRAAG 2 'n Ligte tоu wоrd ааn die kаnt van 'n vertikale muur by punt X vasgemaak. 'n Blоk met onbekende massa is aan die ander punt van die tou Y vasgemaak. Die blok word eenkant toe getrek deur 'n horisontale krag van 50 N, soos in die diagram aangedui en daar gehou. Die blok is dan in ewewig, terwyl die hoek tussen XY en die muur 50° is. 2.1 Teken 'n kragtediagram wat AL die kragte toon wat op die blok inwerk. (3) 2.2 Skryf die grootte van die horisontale komponent van XY neer. (1) 2.3 Bereken die spanning in die tou XY. (2) 2.4 Bereken die vertikale komponent van XY. (2) 2.5 Bereken die massa van die blok. (3) [11] Moet asseblief geen antwoorde in die onderstaande blok oplaai nie.

Life оn Venus hаs been discоvered! Yоu аre pаrt of a Georgia Tech team that is studying a worm-like organism that lives suspended in the cloud banks of Venus. Its nervous system is remarkably like those found on earth despite using several different ions to regulate membrane potential. You find that Venusian neurons at rest are permeable to Fluoride (F-) in addition to Na+, K+ and Cl-. You measure the concentrations of the ions inside and outside their neurons and find the following values and permeabilities. Ion K+ Na+ F- Cl- Concentration outside 10 450 200 60 Concentration inside 435 50 10 10 Permeability at rest 25 1 25 5 (2 pts) Given that these Venusian worms live their short lives on the top surface of the atmosphere’s cloud banks where the temperature is ~37°C (310.15 K), calculate the ionic equilibrium potential of F- (EF-) in their neurons. Show your work (either use equation editor/type out the equation with () or on scratch paper that you turn in with your name & GT ID#) and pay attention to units!
