Aspace probe is sent to the vicinity of the star capella, which
is42.2 light years from the earth. (a light year is the
distancelight travels in a year.) the probe travels with a speed
of0.9910c. an astronaut recruit on board is 19 yearsold
when the probe leaves the earth. what is her biologicalage when the
probe reaches capella?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
