Answer:
See attachment for flowchart
Explanation:
The flowchart is represented by the following algorithm:
1. Start
2. Input Mass
3. Input Volume
4 Density = Mass/Volume
5. Print Density
6. Stop
The flowchart is explained by the algorithm above.
It starts by accepting input for Mass
Then it accepts input for Volume
Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume
Step 5 prints the calculated Density
The flowchart stops execution afterwards
Note that the flowchart assumes that the user input is of number type (integer, float, double, etc.)
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: An operating system(OS) is an interface between the hardware and the user. An OS is built so that it could support other software. OS is a system software which is used to support other application softwares.
Explanation:
An operating system handles all the hardware of the system and allows users access to those hardware components with the help of application softwares.
An OS consist of many libraries and APIs which allows programmers to write and execute codes. There are many types of OS such as real time, multitasking, multi programming OS.
The OS is responsible for allocating memory, managing the hardware, distributing resources across different processors in an distributed system.
So all these features makes them different from application software. The OS is responsible allocating memory and hardware resources to these softwares.
Validation: Understanding and showing acceptance for another person
Answer:
Internal and External Zones
Explanation:
Demilitarized Zone (DMZ) in a network means that, we make sure the security of network at higher level as military make sure the security of their bases or zones.
In this type of network, The network of the internal organization (LAN) needs security from hackers and unauthorized users who are trying to access the resources and information from the network.
This network is divided into two major zones. A DMZ has been placed between two zones along with firewalls enhance the security of LAN Network from the networks on internet. These two zones are named as Internal and External Zone. The firewall between DMZ and External zones monitors the users from external networks on the internet who tries to access organization's network. Internal network monitors the traffic between DMZ and Internal LAN network.
