A book with printing error contains four different formulae for displacement. Choose the correct formula/formulae(a) y = a sin2πt/T (b) y = a sin vt (c) y =a/Tsin(t/a)(d) y =a/T(sin(2π)t/T+cos(2π)t/T) |

Answer» SOLUTION :The argument of sine and cosine function must be dimensionless so (a) is the probable correct FORMULA. SINCE `y=(a)/(t)sin((t)/(a)),because[(t)/(a)]` is dimensional so this is INCORRECT. |
