A package of frozen fish sticks have different instructions when they are heated up on the stove as compared to using the oven.
Stove: Heat over medium flame for 2 minutes. Then flip the fish sticks (turn them over) and heat them for another two minutes.
Oven: Preheat the oven to 375 F. Put them on a metal baking sheet for 15 minutes.
a. Explain why the instructions have you flip the fish sticks over when you’re heating them with the stove, but not with the oven.
b. If you follow the oven instructions, the side of the fish sticks touching the metal baking sheet will cook more than the top side of the fish sticks. Explain why.
When are the thin-walled tubes of the noncircular cross-section often used to construct?
2. Sharp notches are often added to plastic food packages to help open them (along with arrows indicating
where they should be torn). Why do they do this, and why is it sometimes very hard to open them
without this notch? Would it be harder or easier to open with a semi-circular notch and why?
