Multiple choice please help :) At John and Jay's Delicious Cookies test kitchen, engineers want to use materials to make the fastest cooling sheets for cookies after the cookies come out of the oven. The engineers are studying each material's thermal
conductivity, or how easily a material can transfer thermal energy in the form of heat.

Thermal conductivity is
measured in Wim-K.
Based on the information in the table,
Thermal Conductivity
of Different Materials
which material should the engineers use to
make the cooling sheets?

A. copper
B. bronze
C. iron
D. tungsten

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
