Q1

Two simple harmonic motions are represented by the equations

\({x}_{1}=5\sin \left(2\mathrm{πt}+\frac{\pi }{4}\right)\)

\({x}_{2}=5\sqrt{10}\left(\sin 2\mathrm{πt}+\cos 2\mathrm{πt}\right)\)

The ratio of the amplitude of \(x_{1}\) and \(x_{2}\) is

a

\(1\)

b

\(1\ :3\ \)

c

\(1\ :\ 2\)

d

\(1\ :\ 4\)
