`y(x, t) = 0.8//[4x + 5t)^(2) + 5]` represents a moving pulse, where `x` and `y` are in meter and `t` in second. Then

y(x, t) =(0.8)/([(4x + 5t)^(2) +5]) represents a moving pulse where x and y are in metre and t in second. Then,choose the correct alternative(s): (a) pules is moving in positive x- direction (b) in 2 s it will travel a distance of 2.5 m (c) its maximum displacement is 0.16 m (d) it is a sysmmetric pulse
