Adamped harmonic oscillator consists of a block (m = 2.00 kg), a spring (k = 10.0 n/m), and a damping force (f = −bv). initially, it oscillates with an amplitude of 25.0 cm; because of the damping, the amplitude falls to three-fourths of this initial value at the completion of four oscillations. we assume that the damping force does not affect the period of each oscillation. (a) what is the value of b? (b) justify the assumption that "damping force does not affect the period of each oscillation".

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.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
