Answer:

D. 0.05 seconds; 4.5

Step-by-step explanation:

Period-

It is the horizontal distance required for the graph of a periodic function to complete one cycle.

Amplitude-

It is the height from the center line to the peak. It can be calculated by taking the average of highest and lowest points.

From the graph it can be seen that the value of the graph repeats itself after 0.05 seconds, so its period is 0.05 sec.

The maximum point of the graph is located 4.5 units away from the mean line. Hence its amplitude is 4.5
