Which labels belong in the regions marked x and y? x: absorbs energy from the core y: takes longer for photons to move through x: releases energy to the photosphere y: takes longer for photons to move through x: takes longer for photons to move through y: absorbs energy from the core x: takes longer for photons to move through y: releases energy to the photosphere

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
