In addition to having indirect observational evidence for stellar-sized black holes in binary systems, astronomers also have indirect observational evidence of supermassive black holes at the centers of galaxies. If you were tasked with finding a supermassive black hole, what observations could you present as evidence that a supermassive black hole exists in a galaxy?

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?

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.
