Question

PLEASE HELP! A) 6,135º C B) 6,681º C C) 502º C D) 47º C

Answer 1

`\huge \boxed{\mathrm{47\° C}}`

Explanation:

The velocity is given as 358 meters per second.

358 = 20√(273 + t)

Solve for t.

Divide both sides by 20.

17.9 = √(273 + t)

Square both sides.

320.41 = 273 + t

Subtract 273 from both sides.

47.41 = t

Round to nearest degree.

t = 47°C
