Carlos arranges his notes about radioactive decay in a graphic organizer. He wants to add the labels shown. Label 1: Photon Label 2: Positron Label 3: No change in mass number A venn diagram with 2 intersecting circles with the left circle labeled gamma decay and the right labeled beta decay. There is an X in the gamma decay circle. There is a Z in the beta decay circle. There is a Y in the intersecting area. Which is the best region for each label? Label 1: Z Label 2: X Label 3: Y Label 1: X Label 2: Z Label 3: X Label 1: X Label 2: Z Label 3: Y Label 1: X Label 2: Z Label 3: Z

Acar is traveling at 53.0 mi/h on a horizontal highway. (a) if the coefficient of static friction between road and tires on a rainy day is 0.104, what is the minimum distance in which the car will stop?

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

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 ⇒
