Answer:
As a high-quality communication system, online games provide a virtual world where gamers communicate with each other by using rich interactive multimedia. This would facilitate communication among online gamers and enhance the development and maintenance of interpersonal relationships.
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
Answer: (C) Ransomware
Explanation:
The ransomware is one of the type of malware software design which is used for blocking the user accessing unauthorized and also without paying money.
The most of the ransomware software encrypt the computer accessing and the files as they demand for the payment dues for again restoring the access.
It also encrypt the user account and the information until the correct decrypt key are get entered into the system. So, according to the given situation, the ransomware attack are experienced in an organization.
Therefore, Option (C) is correct.
