Q12. The graphs in the figure on the right show the displacement caused by a wave moving along a string at two instants, (a) $t_1$ and (b) $t_2$. Let $v_{av}$ denote the average speed of a piece of string during the time interval between $t_1$ and $t_2$. Compare the wave speed $c$ to $v_{av}$ of a piece of the string at the position $x = a$.

Two identical buildings are built next to each other, just 0.94 meters apart. The buildings are each 35 meters high and are square in shape, seen from the top, with a side length of 19.1 m. When a brisk wind (10.3 m/s) blows against the buildings, inhabitants of the buildings notice that windows will swing open into the space between the buildings if not securely latched. What is the force (in N) on a typical window with a surface area of 1.25 m2 from the wind in this situation? You may assume that 20% of the wind hitting the front of the buildings flows through the gap. You may assume the density of air to be 1.29 kg/m3.
