This is my first yeah doing physics and it’s really hard please help I’ll even mark you

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

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.

Argon, neon, and xenon are examples of
