Imagine a sunny day at the pool. The sun is out and you are thinking about how the light travels from the sun and then hits the water. How does the light react once it hits the water? Draw or insert a model (that you created not Googled) of what you think happens to the light as it hits the water in the space below. Make sure to include an explanation too. Use what you learned to help you.

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction

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

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
