Which is a reason to use digital signals instead of analog signals to transmit information?
A. Noise decreases the loudness of analog signals but does not
affect the loudness of digital signals.
B. The waves used to transmit analog signals are more dangerous
than the waves used to transmit digital signals.
C. Noise changes the quality of analog signals but does not affect
the reliability of digital signals.
D. The waves used to transmit analog signals require more energy
than the waves used to transmit digital signals.

Answerinterdependent

A) the moment of inertia is given by i = mr^2 here m = 0.25 and r = 0.5. i = 0.25 * (0.5)^2 = 0.0625. b) i = 9.74 * 10^(37) and mass = 5.98 * 10^(24) so r^2 = i/m = 9.74 * 10^(37)/5.98 * 10^(24) = 1.628 * 10^(37 - 24) = 1.628 * 10^(13) r = √ 1.628 * 10^(13) = 4034848.200 c) since angular momentum is the product of moment of inertia and angular velocity, a = i * v; but i = mr^2 = 2 * 0.6^2 = 0.72 so a = 0.72 * 1.1 = 0.792. if she pulls her hand in 0.15 m. the new radius = 0.6 - 0.15 = 0.45. v = angular momentum/ radius = 0.792/ 0.45 = 1.76
