Pipin' pete is playing at city park next weekend. one of the closed-end pipes is capable of sounding out a first harmonic of 349.2 hz. the speed of sound in the pipe is 350 m/sec. find the length of the air column inside the pipe. give your answer in meters.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

If anyone who can me with this hw? i would really appreciate it
