80 m

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

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.
