You are designing a new piece of fishing equipment that will allow you to catch a fish from the surface. You know that water refracts (bends) light, but in order to properly program your device, you need to know by what angle water refracts (bends) light. Describe an experiment you would conduct to determine the angle at which water refracts (bends) light.

What happens to the light rays when they hit the specimen?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

You throw a small rock straight up from the edge of a highway bridge that crosses a river. the rock passes you on its way down, 7.00 s after it was thrown. what is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? ignore air resistance.
