Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are and less frequent, and the star or galaxy

(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?

Convection currents are caused by differences in what two things?
