Question

discuss S.H.M. as a special case of circular motion and derive the expression for displacement and relocity of a body executing S.H.M.​

Answer 1

Answer:

Displacement as a function of time in SHM is given byx(t)=Acos(2πTt+φ)=Acos(ωt+φ) x ( t ) = A cos ( 2 π T t + φ ) = A cos ( ω t + φ )

Answer 2

Explanation:

provided with three test tubes. One of them contains distilled water and the other two have an acidic solution and a basic solution respectively. If you are given only red litmus paper, how will you identify the contents of each test tube? 6. HCI, HNO, C,H,OH
