Assuming a 100-W sodium-vapor lamp radiates its energy uniformly in all directions and the wavelength of the light is 589 nm, at what rate are photons emitted from the lamp and at what distance from the lamp will the average flux of photons be 1 photon/cm2

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.

What’s #16 asking and how do i solve it?

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
