An object moves with constant acceleration 4.80 m/s2 and over a time interval reaches a final velocity of 13.8 m/s. (a) If its original velocity is 6.90 m/s, what is its displacement during the time interval? m (b) What is the distance it travels during this interval? m (c) If its initial velocity is −6.90 m/s, what is its displacement during this interval? (d) What is the total distance it travels during the interval in part (c)?

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) ! : )

Frequency of electromagnetic waves that a radio station is assigned is called

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
