The chart shows data for four moving objects. A 4 column table with 4 rows. The first column is labeled Object with entries, W, X, Y, Z. The second column is labeled Initial Velocity in meters per second with entries, 11, 10, 12, 20. The third column is labeled Final Velocity in meters per second with entries, 29, 34, 40, 28. The fourth column is labeled Change in Time in seconds with entries, 6, 12, 7, 8. Which object has the greatest acceleration? W X Y Z

In a system, when potential energy decreases, then entropy also decreases. true false

What is a neurotransmitter involved in mood reward, addiction, and motor behaviors?

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
