The equation of the wave is Y =10 ( 2 t 30 + ) If the displacement is 5 ~cm at t =0 then the total phase at t =7.5 ~s will be ( 30^ =0.5 )

Options

  1. A3 rad
  2. B2 rad
  3. C2 5 rad
  4. D2 3 rad

Correct answer

D. 2 3 rad

Step-by-step solution

array ll & At t =0,10 ( 2 0 30 + )=5 & 10 =5 & =0.5 & = 6 array Thus, at t =7.5 ~s , 10 ( 2 7.5 30 + )=10 ( 2 + 6 ) The total phase is 2 3 .
