Coastal towns should protect themselves from floods by building sand walls that keep out water from oceans, lakes, and rivers. However, some say that these sand walls are an eyesore. They reduce the value of the homes and buildings that they try to protect because they look bad.
Which statement presents the best rebuttal to address the counterclaim?
The value of the coastal homes is more important than oceans, lakes, and rivers.
The protection of homes and buildings in coastal towns with sand walls is important.
Sand walls may be ugly, but the protection of people and property is more important.
People living along the coasts should seriously consider moving further inland.

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
