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: true
Explanation:
As the operating system cannot run from an external device and in a distributed operating system all the clients needs to be connected to the network to share resources via the distributed or network operating system.
Answer:
Threat disgruntled employees
Explanation:
This is a type's threat in a network, why disgruntled employees is a threat?
Because disgruntled employees can implement a plant to damage a company's system when an IT employee be fired.
I t can be difficult to try to protect a system of these threats, Traditionally companies can wait for the less damage, then delete those credentials.
In cloud computing we have IDaaS, where an external company administers the company's credentials, is harder to damage the system in this way.
Answer:
The answer to this question is given in the explanation section.
Explanation:
This is a type of software which show us data in tabular form. These software can easily store, analyze and organize data.
They are divided in rows and columns. They are mainly used for accounting and book keeping.
The commonly used spread sheet software in the market are MS Excel by Microsoft, Calc by libre office.
Not sure whether this question is requires a specific answer but I would say Waze.
