Question

need answer fast please​

Answer 1

Answer:

(A):-M^0L^0T^0

Explanation:

2ωsin(ωt+∅)

sin(ωt+∅)=constant

Suppose value of sin(45°)=1/√2

conclusion:-

Anything inside the trigonometric functions (tan,sin,cos,cosec,cot,sec) have constant values so dimensional formula of such functions will be M^0L^0T^0.
