Here are three stress v strain graphs shown on approximately the same scale. Stress B A С Strain a) Match each graph to one of either copper, glass or rubber. Give a reason for each of your choices, perhaps making reference to the grey circular points. b) Explain with the aid of a stress v strain graph why an elastic band becomes warm after stressing and being allowed to return to its original length. c Explain how the Young's modulus for rubber describes the shape of its graph. W

what are the options.

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
