Question

a cat napping in the sun near a window is warmed by what type of energy transfer?
radiation from the sun
both convection and conduction from the sun

Explanation:

Step1: Recall heat transfer methods

Heat transfer occurs via conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves).

Step2: Analyze the sun - cat scenario

The sun's energy reaches the cat through space (no direct contact or fluid medium for conduction/convection). Sun emits electromagnetic waves (radiation).

Answer:

radiation from the sun
