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:

Answer:
Advantages: computers don't make human error
It can be used for communication
Ease of access
Disadvantages: computers can be a distraction
Potential loss of privacy
It can limit learning and create a dependency
Answer:
a. new, running, waiting, ready, and terminated.
Explanation:
The process in a computer system can have different states and these are:
-New: When the process is created.
-Ready: When the process is waiting to be executed.
-Running: When the process is chosen to be executed.
-Waiting: When the process is expecting for something to happen.
-Terminated: When the process is not running anymore.
According to this, the answer is that the possible states of a process are: new, running, waiting, ready, and terminated.

Explanation:
Data values in a program are held in variables. Variables are like containers for holding different types of data. A variable can be identified depending on the kind of data it holds. Variables can hold data types of integers, strings, arrays, lists, sets, Boolean etc. They hold unique data types and a can not hold different data types. Different rules exist for naming variables in different programming languages. A variable name should start with lowercase letters and be descriptive of the data it holds.
