How is technology useful and how is it harmful

Lelu [443]

Explanation:

The aggregation of methods used in order to accomplish a goal is called technology.

Whether technology is used to accomplish a goal which society does not deem acceptable then the goal is bad. The same technology can be used to do good. So, the question whether technology is harmful or useful depends on the goal a person wasts to acheive.

Let us take an example

The internet is one of the greatest discoveries of mankind which allows people access to unlimited information. It can be used for a variety of different services such buying goods and services. However, the internet is also a technology that facilitates illegal activities that circumvents government intervention. This way of technology being used is harmful.

The density of a pure liquid at 25 degrees Celsius was calculated by determining the mass and volume of a sample of the liquid.

adelina 88 [10]

Answer

The density of the liquid is 0.82 g/mL.

Explanation:

From the question given above, the following data were obtained:

Mass of empty flask = 18.990 g

Mass of flask + liquid = 39.439 g

Volume of liquid = 25 mL

Density of liquid =..?

Next, we shall determine the mass of the liquid. This can be obtained as follow:

Mass of empty flask = 18.990 g

Mass of flask + liquid = 39.439 g

Mass of liquid =.?

Mass of liquid = (Mass of flask + liquid) – (Mass of empty flask)

Mass of liquid = 39.439 – 18.990

Mass of liquid = 20.503 g

Finally, we shall determine the density of the liquid as follow:

Mass of liquid = 20.503 g

Volume of liquid = 25 mL

Density of liquid =..?

Density = mass / volume

Density of liquid = 20.503 / 25

Density of liquid = 0.82 g/mL
