Answer:

correct answer

Explanation:

1. Max value is 42.42

2. Frequency is 628/(2*pi), so about 100 Hz

3. RMS value of a sine wave is amplitude/sqrt(2)

so in this problem it's 42.42/sqrt(2) = about 30.0

4. "Average value" in this context usually means

average absolute value, which is

(2/pi)*amplitude = about 27
