Answer: The expected population that wants flexible working hours in ranging from 58% to 62 %.
Explanation:
Percentage of sample respondents agreed for flexible working hours = 60%
The margin of the error = ± 2%
The expected population that wants flexible working hours in ranging from:
lower range
upper range
that is 58% to 62 %.
The expected population that wants flexible working hours in ranging from 58% to 62 %.
Series ..... 2 ohms. Parallel ..... 1/2 ohm.
Answer:
α = 1215.71 rad/s²
Explanation:
The angular acceleration of an object is defined as the time rate of change of angular velocity of he object. The formula for the angular acceleration of an object is given as follows:
α = (ωf - ωi)/Δt
where,
α = angular acceleration of the disk = ?
ωf = Final Angular Velocity = 0 rad/s (Since disk finally stops)
ωi = Initial Angular Velocity = (5050 rpm)(2π rad/rev)(1 min/60 s)
ωi = 528.83 rad/s
Δt = time interval = 0.435 s
Therefore,
α = (0 rad/s - 528.83 rad/s)/(0.435 s)
α = - 1215.71 rad/s²
here, negative sign indicates that the direction of acceleration is opposite to the direction of angular velocity or the angular motion. So, the magnitude of acceleration will be:
<u>α = 1215.71 rad/s²</u>
Answer:
Explanation:
Let the height of the tree is y and the distance of tree from point B is x.
According to the diagram
x = 0.55 y ..... (1)
(50 + 0.55y) 1.17 = y ..... from equation (1)
58.5 + 0.644 y = y
0.356 y = 58.5
y = 164.3 ft
