A55.0-gram lead bullet hits a steel plate, both initially at 24 °c. the bullet melts and splatters on impact. assuming that the bullet receives 72% of its kinetic energy as heat energy, at what minimum speed must it be traveling to melt on impact? (the melting temperature of lead is 327°c)

On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the youngest unit in the center, the underlying structure is a(n)

Which of these metals are magnetic?

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?
