A7.5-cmcm-diameter horizontal pipe gradually narrows to 4.5 cmcm . when water flows through this pipe at a certain rate, the gauge pressure in these two sections is 32.0 kpakpa and 25.0 kpakpa , respectively.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Física: un futbolista patea hacia el arco con una velocidad de 15m/ah, calcular: a)el alcance para un ángulo de tiro de 25? , b) el tiempo que el balón permanece en el aire.

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) ! : )
