Lily has noticed that all of her friends love to talk about their flaws. No matter what they start talking about, the conversation turns to social media and picking apart celebrities’ bodies and eventually their own. Lily is starting to wonder if this is the right friend group for her because she finds all of this negativity exhausting. What advice would you give Lily? A.
If she has a good body image, all of that negativity will not be a problem.
B.
Lily will have the same body image as her friends, so she must dump these friends.
C.
If changing the subject does not work, it would be good to find some positive people.
D.
Her friends are clearly not interested in developing healthy habits and enjoy complaining.

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 ⇒
