Amonatomic gas is measured to have an average speed of 1321 m/s. if the total amount of the gas is 5 mol (which equates to a mass of 0.02 kg), what is the approximate temperature of the gas? (recall that the equation for kinetic energy due to translation in a gas is translational = mv2 = nrt, and r = 8.31 j/(mol a. 350 k b. 300 k c. 280 k d. 320 k

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
