How much of Cam Newton's yardage was for passing?, Context: The Panthers offense, which led the NFL in scoring (500 points), was loaded with talent, boasting six Pro Bowl selections. Pro Bowl quarterback Cam Newton had one of his best seasons, throwing for 3,837 yards and rushing for 636, while recording a career-high and league-leading 45 total touchdowns (35 passing, 10 rushing), a career-low 10 interceptions, and a career-best quarterback rating of 99.4. Newton's leading receivers were tight end Greg Olsen, who caught a career-high 77 passes for 1,104 yards and seven touchdowns, and wide receiver Ted Ginn, Jr., who caught 44 passes for 739 yards and 10 touchdowns; Ginn also rushed for 60 yards and returned 27 punts for 277 yards. Other key receivers included veteran Jerricho Cotchery (39 receptions for 485 yards), rookie Devin Funchess (31 receptions for 473 yards and five touchdowns), and second-year receiver Corey Brown (31 receptions for 447 yards). The Panthers backfield featured Pro Bowl running back Jonathan Stewart, who led the team with 989 rushing yards and six touchdowns in 13 games, along with Pro Bowl fullback Mike Tolbert, who rushed for 256 yards and caught 18 passes for another 154 yards. Carolina's offensive line also featured two Pro Bowl selections: center Ryan Kalil and guard Trai Turner.

The most heat-treatable alloys are decided but only?, Context: Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.
