Answer: O furo diminui enquanto a chapa aumenta a sua dimensão.
(The diameter decreases and the dimensions of the metal increases)
Explanation:
I will answer in English:
Here we have a piece of metal with a small hole on it, that is heated in a hoven.
We know that when a piece of metal is heated, it will expand (the density decreases, so the dimensions of the piece of metal increase).
Now, particularly, the hole will also expand but inwards, as each "extreme" of the piece of metal, will expand into where it has less resistance, so it will expand in the region where there is no material. This "inwards" expansion is why the diameter of the hole will decrease.
Answer:
acceleration m/s²
Explanation:
The units on the left side of the equation are units of length. The units on the right side of the equation must be units of length also. Acceleration times time squared gives length.
You need to check the temperature of food being stored in a temperature-controlled environment every four hours. The process of changing a space's temperature is called temperature control.
Cooking food alone may not be enough to avoid food poisoning, though, if the bacteria in food are allowed to grow to large numbers. When the temperature is between 5°C and 63°C, bacteria can grow. The risk zone is the range between 5°C and 63°C.
Temperature control is a process where the passage of heat energy into or out of a space or substance is adjusted to achieve the desired temperature. This process involves measuring or otherwise detecting changes in the temperature of the space (and all of the objects contained therein) or of the substance.
