These objects are labeled seaweed negative 20 meters, clownfish negative 23 meters, squid negative 44 meters. What did the diver most likely use as a reference point to describe the position of the squid? the ocean surface the ocean floor the position of the clownfish the position of the seaweed

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

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
