Answer:

<u>The internet of things (IoT)</u>

Explanation:

With the advance in technology comes about new ways of performing tasks. A typical example of the application of new technology in this scenario is the Internet of things (IoT).

<em>The Internet of Things (IoT) </em>simply put involves a network that allows physical devices or things to be <em>interconnected</em> with sensors and software that allows for these physical devices to learn new patterns and to exchange data between the network.

Answer:

The Internet of things

Explanation:

When devices embedded with a network connectivity, software or sensors, are able to exchange data with the manufacturer through the network of physical things, then we say the Internet of things (IoT) has been defined.

Internet of things is when devices like smartphones, sensors and other smart devices are connected together which allows them to exchange data through the network of physical things. By exchanging data, these devices learn new patterns of adaptation.

In this case, the fly thermostat, learns the patterns for raising and lowering the temperature in a house through the Internet of things beacause the sensor has made it possible by automatically observing the temperature pattern of the house.

Find the resultant of two forces 130 N and 110 N respectively, acting at an angle whose tangent
monitta

Answer:

F_r = 200N

Explanation:

Given

Let the two forces be

F_1 = 130N

F_2 = 110N

and

\tan(\theta) = \frac{12}{5}

Required

Determine the resultant force

Resultant force (Fr) is calculated using:

F_r^2 = F_1^2 + F_2^2 + 2F_1F_2\cos(\theta)

This means that we need to first calculate \cos(\theta)

Given that:

\tan(\theta) = \frac{12}{5}

In trigonometry:

\tan(\theta) = \frac{Opposite}{Adjacent}

By comparing the above formula to \tan(\theta) = \frac{12}{5}

Opposite = 12

Adjacent = 5

The hypotenuse is calculated as thus:

Hypotenuse^2 = Opposite^2 + Adjacent^2

Hypotenuse^2 = 12^2 + 5^2

Hypotenuse^2 = 144 + 25

Hypotenuse^2 = 169

Hypotenuse = \sqrt{169

Hypotenuse = 13

\cos(\theta) is then calculated using:

\cos(\theta)= \frac{Adjacent}{Hypotenuse}

\cos(\theta)= \frac{5}{13}

Substitute values for F_1, F_2 and cos(\theta) in

F_r^2 = F_1^2 + F_2^2 + 2F_1F_2\cos(\theta)

F_r^2 = 130^2 + 110^2 + 2*130*110*\frac{5}{13}

F_r^2 = 16900 + 12100 + 11000

F_r^2 = 40000

Take square roots of both sides

F_r = \sqrt{40000

F_r = 200N

<em>Hence, the resultant force is 200N</em>
