A3 inch fire hose has a water flow of 200 gallons per minute. what is the flow in liters per second? note: use us gallons not uk gallons. (10 points) the blower on an air conditioning unit produces 95 cubic feet per minute of air in the ductwork. what is the air flow in cubic meters per hour? m/hr (10 points) torque (or moment) is the measure of turning force or twist on an object. if a mechanic is applying 12 newton centimeters of torque on a bolt how many pound inches would this be?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
