Some examples of environmental technology is recycling.
Banded rows indicate that there are different formatting for odd and even rows.
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:
the answer is going to be c
We have that the .xlsm <em>Format </em>is used to save Excel Macro-Enabled Workbook file
<h3>Formats</h3>
Generally file are saved in different formats for easy sorting and application on the operating system.
For instance if a music file is renamed and stored in a different format say .exe the audio file wont be recognised as an audio file and hence refuse to play.
e.g
- .exe for a windows appication
- ,mp3 for an audio file
- .xlsm here is used to save Excel Macro-Enabled Workbook file
