Orb spiders make silk with a typical diameter of 0.15 mm. the young's modulus of spider silk is 0.2×1010n/m2 and its tensile strength is 1000×106n/m2.part a: a typical large orb spider has a mass of 0.50 g. if this spider suspends itself from a single 12-cm-long strand of silk, by how much will the silk stretch? (answer in mm)part b: what is the maximum weight that a single thread of this silk could support? (answer in n)

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
