new to physics can some one plz help me with b and c Load (kN) 0 20 30 50 60 73 90 94 Extension (mm) 0 0.150 0.225 0.375 0.453 0.550 0.900 1.100 a) Draw a graph with load on the y-axis and extension on the x-axis (a load extension graph). Title the graph and Label the axis. b) The diameter of the wire is 0.00735 m and its length is 36.75 mm. Determine the modulus of elasticity, E of the sample wire. c) Select from the graph an appropriate point for the elastic limit of the wire and give the value of the: (i) load, (ii) stress if the diameter is 0.00735 mm.
