A 12.58 kg block is slid from a height of 9.16 m down a friction-less incline. It comes to a flat surface and crosses a 5.89 m strip of sandpaper with a coefficient of friction of 0.32. After passing over the sandpaper, the block is traveling on a friction-
less surface again. How fast is the block traveling?

Ais useful when you need a simple machine to you separate two things. a. lever b. screw c. pulley d. wedge

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.
