A2.36 kg block resting on a frictionless surface is attached to an ideal spring with spring constant k = 260 nm . a force is applied to the block which changes its position from xi=5.89 cm to xf=−15.4 cm , each distance measured relative to the equilibrium position of the block. while the block is being moved, find
(a) the work done by the spring and
(b) the work done by the applied force.

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.
