Vittorio needs to clean the dusty mirror hanging on the wall beforehe can use it, but he would like to clean as little of the mirroras possible.
a) vittorio would like to be able to see the logo on his shirt. draw the incident and reflected raysshowing the light from the logo reflecting off the mirror into hiseyes. the rays should meet at the point on the mirror that needscleaning. question 2:
vittorio would like to be able to check whether his shoelaces aretied. draw the incident and reflected rays showing the light fromhis shoelaces reflecting off the mirror into his eyes. again, therays should meet at the point on the mirror that needscleaning.

What is the relationship between the direction of motion of the balloon and the wind currents

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
