You’re making a food safety mistake if you

Physics

Strike441 [17]3 years ago

The answer is; D

Cooking food kills bacteria. Putting it while still warm in the fridge gives a thermal shock to the remaining bacteria hence also acts towards positive food safety. Fridging food reduces reproduction rates of bacteria on the food hence their colonies cannot grow.  Allowing the food to cool before putting it in the fridge give time for bacteria colonies to settle on the food again.

Answer: Option D

Explanation: There are certain safety guidelines that should be maintained while preparing and storing food. These guidelines helps to keep the food healthy and prevents from spoilage.

One of the safety guidelines states that food should not be kept outside until it cools down and then putting it inside the refrigerator. The bacteria can grow in the food within two hours unless it is refrigerated.

So, it should be kept inside the refrigerator before two hours.

taurus [48]

Answer:

Equipment grounding conductor.

Explanation:

EGC ( Equipment grounding conductor) is used to ground the non current carrying metal parts of equipment. It provides a safe path for the flow of ground fault current by keeping the equipment close to the ground potential. It can be apply in the above mentioned case for grounding electric signs and metal equipment of outline lighting system. So we can say that Electric signs and metal equipment of outline lighting systems, other than the portable and double-insulated types, shall be grounded by connecting them to the <u>Equipment grounding conductor</u> of the supplying branch circuit or feeder.

What are some potential sources for error in conducting research?
harina [27]

Population specification errors occur when the researcher does not understand who they should survey. This can be tricky because there are multiple people who might consume the product, but only one who purchases it, or they may miss a segment looking to purchase in the future.

Measurement error is generated by the measurement process itself, and represents the difference between the information generated and the information wanted by the researcher. Generally, there is always some small level of measurement error due to uncontrollable factors.

In an insulated container, liquid water is mixed with ice. What can you conclude about the phases present in the container when
natulia [17]

Answer:

There is no way of knowing the phase composition without more information

Explanation:

For equilibrium to be established quantity of heat loss by the water must equal to the quantity of heat gain by the ice since the container is insulated which rules out loss of heat to the environment. To be able to the determine the phases present we need the temperature of the water as well as the temperature of the ice, mass of the water present and the mass of the ice . These two are not given, we therefore do not have enough information to determine the phases present even when we can easily get the values of specific heat capacity and latent heat of fusion.

Three ice skaters, numbered 1, 2, and 3, stand in a line, each with her hands on the shoulders of the skater in front. Skater 3,
BlackZzzverrR [31]

Answer:

Following are the responses to the given question:

Explanation:

The mass (mg) is downwards, the typical N_2 pressure is upward. This pushing force of \vec{F}_{3 \to 2} is pushed forward by skater 3 on skater 2. (considered as rightward direction). The strength of the slater 2 in reply is the slater \vec{F}_{2\to 3} Skater three moves to the left.

Its push force \vec{F}_{2\to1} imparted to the skateboarder 2 in relation those above forces The force\vec{F}_ {1\to 2} on skater 2 by skater 1 is as a response, to a left. Skater 2's free body system is as follows:

Helppp please I’m have no time quick please
kolezko [41]

Answer:

I = 1.09 A

Explanation:

Here, 5 ohm and 12 ohm resistor are connected in parallel. Using the parallel combination of resistors as follows :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{R}=\dfrac{1}{5}+\dfrac{1}{12}\\\\ R=3.52\ \Omega

Now R and 2 ohm resistors are in series. Let the equivalent be R_{eq}. So,

R_{eq}=3.52+2\\\\=5.52\ \Omega

Let I be the current. Using Ohm's law,

V = IR

I=\dfrac{V}{R_{eq}}\\\\I=\dfrac{6}{5.52}\\\\I=1.086\ A

or

I = 1.09 A

So, the correct option is (c).
