-
A.
2700 -
B.
450 -
C.
900 -
D.
1800 -
E.
No Correct Option
Correct Answer: Option E
Explanation
Comparing y = 10Sin( (1000pi t – frac{pi x}{34} ) \
text{With } y = a text{Sin }(net – kx)\
K = frac{pi}{34}, text{and phase difference}\
J = KAC = frac{pi}{34} times 1.53rad.\
text{But} pi rad = 180^0 \
text{Therefore } frac{1.53rad}{34} = frac{1.53 pi}{34} times frac{1}{pi} times 180^0 \
=8.1^0 )
