The displacement of a particle in a medium can be expressed as
`y=10^(-6)sin(100t+20x+pi//4),`
where x is in metre and t is in second. What is the speed of the wave?

The displacement y of a partcle in a medium can be expressed as, y = 10^(-6) sin ((100t + 20x + (pi)/(4))m where t is in second and x in meter. The speed of the wave is

The displacement y of a partcle in a medium can be expressed as, y = 10^(-6) sin ((100t + 20x + (pi)/(4))m where t is in second and x in meter. The speed of the wave is

The displacement y of a particle in a medium can be expressed as y = 10^(-6) sin (100t+20 x+ (pi)/(4))m where 't' is in second and x in metre. The speed of wave is

The displacement of particle in a medium can be expressed as y=10^(-6)sin(100t-20x+pi//4) m, where t is in seconds and x in meters. The speed of the wave is

The displacement y of a particle in a medium can be expressed as y = 10^(-4) sin (10 t + 2x + pi//4) where all quantities are in SI units. Find the speed of the wave.

The displacement y of a particle in a medium can be expressed as y =10^(-6) wSin(100t+20x), where t and x are in second and metre respectively. Calculate the speed of the wave.
