Alan is evaluating different biometric systems and is concerned that users might not want to subject themselves to retinal scans due to privacy concerns. Which characteristic of a biometric system is he considering

Answers

Answer 1

Alan is considering the user acceptance characteristic of a biometric system.

This refers to the extent to which users are willing to use the system and subject themselves to the biometric identification process. In this case, Alan is concerned that users may be hesitant to undergo retinal scans due to privacy concerns. User acceptance is an important characteristic to consider when evaluating biometric systems, as it can affect the system's overall effectiveness and adoption rate. Biometric systems with high user acceptance are more likely to be successful in various applications, including security, access control, and identity verification. Therefore, it is important to carefully consider user acceptance when selecting and implementing biometric systems.

a 958 g sample of liquid h2o is placed in the freezer and allowed to completely freeze. determine the amount of heat transferred during the freezing in kj.

Answers

To determine the amount of heat transferred during the freezing of a 958 g sample of liquid H2O, we need to consider the heat of fusion and the specific heat capacity of water.

The freezing process involves the transfer of heat from the water to the surroundings until it reaches the freezing point and turns into solid ice.

The heat transferred can be calculated using the equation Q = m * ΔHf, where Q is the heat transferred, m is the mass of the substance, and ΔHf is the heat of fusion.

In this case, the mass of the water sample is given as 958 g. To determine the heat transferred during freezing, we need to know the heat of fusion for water, which is 334 J/g. However, since the answer should be in kilojoules (kJ), we need to convert the mass to kilograms. Therefore, the mass of the water sample is 0.958 kg.

Using the formula Q = m * ΔHf, we can calculate the heat transferred. Substituting the values, we have Q = 0.958 kg * 334 J/g. Now we need to convert the result from joules to kilojoules by dividing by 1000. The final calculation is Q = (0.958 kg * 334 J/g) / 1000 = 0.320 kJ.

Therefore, the amount of heat transferred during the freezing of the 958 g sample of liquid H2O is approximately 0.320 kJ.

I sometimes fancy that in my condition if I had less opposition and more society and stimulusbut John says the very worst thing I can do is to think about my condition, and I confess it always makes me feel bad, so I will let it alone and talk about the house. It's the most beautiful place and is quite alone, standing well back from the road, quite three miles from the village. It makes me think of English places that you read about, for there are hedges and walls and gates that lock, and lots of separate little houses for the gardeners and people. There is a DELICIOUS garden! I never saw such a gardenlarge and shady, full of box-bordered paths, and lined with long grape-covered arbors with seats under them. There is a something strange about the houseI can feel it. I even said so to John one moonlit evening, but he said what I felt was a DRAFT and shut the window. I don't like our room a bit; I wanted one downstairs that opened on the piazza and had roses all over the window and such pretty old-fashioned chintz hangings, but John would not hear of it. I have a schedule prescription for each hour in the day, and he takes all care from me, so I feel basely ungrateful not to value it more. He said we came here solely on my account and that I was to have perfect rest and all the air I could get, so we took the nursery at the top of the house. It is a big, airy room, the whole floor nearly, with windows that look all ways, and air and sunshine galore. It was a nursery and then a playroom, for the windows are barred for little children.
