Question

3. What is the period of a periodic wave that has a

frequency of 60. hertz?
A. 1.7 x 10-2 s
S
B. 2.0 × 104 s
S
C. 3.0 × 10-3 s
D. 3.3 × 102 s

Answer 1

a is the correct answer

Step-by-step explanation:

period T=1/f

where f=60hertz

then T= 1/60 which give 0.01666666 but putting it in standard form and rounding up give 1.7×10^-2
