Answer:

Direct voice communication.

Explanation:

Electronics, compared to electrical appliances are low powered logical devices, which uses digital signals of 1s and 0s to represent voltage range. The evolution of these devices have promoted information technology from high quality digital signal transmission to recorded speech platform.

Speech signals could not be recorded before the electronic era, it was only disseminated from one person to another to converted to text for easy and uncorrupted information transfer.

A computer hard disk starts from rest, then speeds up with an angular acceleration of 190 rad/s2 until it reaches its final angu
Nataly_w [17]
The first thing we are going to do is find the equation of motion:
 ωf = ωi + αt
 θ = ωi*t + 1/2αt^2
 Where:
 ωf = final angular velocity
 ωi = initial angular velocity
 α = Angular acceleration
 θ = Revolutions.
 t = time.
 We have then:
 ωf = (7200) * ((2 * pi) / 60) = 753.60 rad / s
 ωi = 0
 α = 190 rad / s2
 Clearing t:
 753.60 = 0 + 190*t
 t = 753.60 / 190
 t = 3.97 s
 Then, replacing the time:
 θ1 = 0 + (1/2) * (190) * (3.97) ^ 2
 θ1 = 1494.51 rad
 For (10-3.97) s:
 θ2 = ωf * t
 θ2 = (753.60 rad / s) * (10-3.97) s
 θ2 = 4544,208 rad
 Number of final revolutions:
 θ1 + θ2 = (1494.51 rad + 4544.208 rad) * (180 / π)
 θ1 + θ2 = 961.57 rev
 Answer:
 the disk has made 961.57 rev 10.0 s after it starts up

4. It exposes teacher and students to more knowledge and opportunities

5. The school governing body can access people and the community's opinions about ways to improve the school better.

6. It exposes the school to more ideas and opportunities.

owever, sitting in a corner of the store, a hacker had just set up an open "rogue" wireless hotspot posing as the coffee shop’s
Ivenika [448]

However, sitting in a corner of the store, a hacker had just placed up an open “rogue” wireless hotspot posing as the coffee shop’s wireless network. When Sarah logged onto her bank’s website, the hacker hijacked her session and gained access to her bank accounts. Another term for rogue wireless hotspots exists as “evil twin” hotspots.

<h3>What is meant by wireless network?</h3>

A computer network is referred to as a wireless network if radio frequency (RF) links are used to connect network nodes. A common solution for households, companies, and telecommunications networks is wireless networking. Wi-Fi is a wireless networking technology that enables printers and video cameras to connect to the Internet as well as computers (laptops and desktops), mobile devices (smart phones, wearables, etc.), and other devices.

Increased Mobility: Wireless networks give mobile users access to real-time data, enabling them to move freely across the premises of your firm without losing network connectivity. This improves collaboration and production across the entire organisation, which is not achievable with traditional networks.
