Which of these explanations is describing the law of inertia?" The seat belt must apply more force to stop a child with more mass than a child with
less mass.
If the car stops suddenly, the seat belt and car seat help overcome the inertia of the
child so the child doesn't keep moving and get injured.
When the seat belt pushes on the child, the child pushes back on the seat belt
None of these are examples of the law of inertia

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
