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

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
