Esmeralda was testing the direction of current in a wire by seeing how the current moved in a magnetic field. She placed two bar magnets next to each other, with a small gap in between. The north pole of one magnet was on the left, and the south pole of the other was on the right. She placed the wire in the gap between the magnets and turned on the current. If the current was flowing towardsEsmeralda, in which direction would the wire move?A upwardB downwardC leftD right

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3

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
