Why does a shirt appear white outside on a sunny day?
Color is a result of the absorption and reflection of light. A
shirt appears a color because it reflects that color of light. A
shirt appears black when it absorbs all wavelengths of light.
The light is transmitted through the shirt, so no color
appears.
© The shirt absorbs the sunlight, so it appears white.
All the light is reflected, so the shirt appears white.
The sunlight refracts when it hits the shirt, so the shirt
appears white

(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?
