Q. A parabolic pulse given by equation $y$ (in $c m) = 0.3 - 0.1 (x - 5 t)^{2} (y \geq 0) x$ in meter and $t$ in second travelling in a uniform string. The pulee passes through a boundary beyond which its velocity becomes $2.5 m / s$ . What will be the amplitude of pulse in $mm$ in this medium after transmission.

Q. A parabolic pulse given by equation y (in cm)=0.3−0.1(x−5t)2(y≥0)x in meter and t in second travelling in a uniform string. The pulee passes through a boundary beyond which its velocity becomes 2.5m/s. What will be the amplitude of pulse in mm in this medium after transmission.
