Acylindrical rod of brass originally 0.40 in (10.2 mm) in diameter is to be cold worked by drawing. the circular cross section will be maintained during deformation. a cold-worked tensile strength in excess of 55,000 psi (380 mpa) and a ductility of at least 15 %el are desired. further more, the final diameter must be 0.30 in (7.6 mm). explain how this may be accomplished

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
