Answer: the sample is not representative of the community.
Explanation:
Online surveys or surveys in general are made to obtain relevant information about a particular issue. If samples are not representative of that issue, they end up having little use.
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:
c i think it mit be right i'm sorry if it's not ,
Explanation:
it's c or D.
Answer:
The correct option : b. new GridLayout(4,3)
Explanation:
The total number of rows are 4 and total number of columns are 3.
So the total keys can be added is 4*3=12. This is suited for telephone keypad.
