In order to answer the question, we convert the measurements given to a common base unit. For this case, we use seconds.
A) 0.02 seconds B) 0.02 teraseconds x (10^12 s / 1 terasecond) = 2x10^10 seconds C) 2,500 milliseconds x (1 s / 1000 ms) = 2.5 seconds D) 25,000 nanoseconds x (1 x 10^-9 s / 1 nanosecond) = 2.5 x 10^-5 seconds <span> Therefore, among the choices listed above the correct answer is D.</span>
To answer the question, convert all of these measurements to a common unit. I choose seconds as the basis.
(a) 0.02 seconds (b) 0.02 teraseconds x (10^12 s / 1 terasecond) = 2x10^10 seconds (c) 2,500 milliseconds x (1 s / 1000 ms) = 2.5 seconds (d) 25,000 nanoseconds x (1 x 10^-9 s / 1 nanosecond) = 2.5 x 10^-5 seconds The answer is letter D.
