Our Sun will eventually turn into a red giant and, finally, a white dwarf. Use the Hertzsprung-Russell diagram to describe how the Sun's luminosity and temperature
will change as it goes through these stages.

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)
