Approximately how long will it be before they are cool enough to eat at 160 degrees f?

you take a pan of brownies out of the oven and set them on the counter in a room that is 70 degrees f, if the brownies start at 400 degrees f, approximately how long will it be before they are cool enough to eat at 160 degrees f? use newton's law of cooling with k = 0.035.

jjj89t'ji; it hink the answer is your mom is not si

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
