The bob of a pendulum swings back and forth with a total mechanical energy of 300 j. what is the kinetic energy of the bob when it is at the lowest point of its trajectory? assume that friction does not affect the pendulum.

200 j

150 j

300 j

0 j

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.
