Physics Question on Work-energy theorem
A wave executes a periodic motion y=2sinπ44t+x2. What is the frequency?
A
(A) 0.5 Hz
B
(B) 1.0 Hz
C
(C) 0.25 Hz
D
(D) 2.0 Hz
Answer
(A) 0.5 Hz
Explanation
Solution
Explanation:
Given that:y=2sinπ44t+x2=2sinπt+πx8A = 2; w= π rad/sω=2πff=0.5 HzHence, the correct option is (A).
