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
Hi!
The mouse and the keyboard are <em>input devices. </em>By using them, we can input data which will give us a (hopefully) desired output!
For example...
Just by using my keyboard to type, I'm inputting data in the form of ASCII characters and symbols.
By using my mouse to click on an area so I can move this sentence on a new line, I had to input a request to do such!
Hopefully, this helps! =)
First three bytes of the ethernet address exists assigned to vendors to identify the equipment.
<h3>What is Ethernet address?</h3>
A media access control address stands for a unique identifier allocated to a network interface controller for usage as a network address in communications within a network segment. This use exists as standard in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
This address exists as the identifying mark that allows a networked computer to communicate with the Internet. The ethernet address exists how we can associate an “IP address” to an individual computer — without this– number, there's no form to access any servers, websites, email, etc.
The first three bytes (pairs of hexadecimal characters) of any unicast address include that vendor address component of the MAC address. The staying three bytes carry the serial number of that vendor's interface card. Dell, Inc. Apple, Inc.
Hence, first three bytes of the ethernet address exists assigned to vendors to identify the equipment.

Mike needs to write the primary objectives of a project in a project plan. He should write this under the SCOPE section of the project plan.
Explanation:
- Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, features, functions, tasks, deadlines, and ultimately costs.
- It is what needs to be achieved and the work that must be done to deliver a project.
- The Scope of Work (SOW) is the area in an agreement where the work to be performed is described.
- The SOW should contain any milestones, reports, deliverables, and end products that are expected to be provided by the performing party. The SOW should also contain a time line for all deliverables.
- The scope is simply all the work that needs to be done in order to achieve a projects objectives.
- A project scope, or project scope statement, is a tool used to describe the major deliverables of a project including the key milestones, high level requirements, assumptions, and constraints.
