I need 2 examples for each of thes helppp!! Chemical energy turning into kinetic energy (something explodes)

Potential energy turning into kinetic energy (something goes down)

Electrical energy turning into kinetic energy (something motorized)

Chemical energy turning into thermal energy (something burns)

Increasing potential energy (something goes up)

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
