Mostly when your around carpet or anything related to a carpet because when you do it long enough you will generate static electricity i hope this helps
Answer:
0.8 m
Explanation:
Draw a free body diagram. There are three forces:
Weight force mg pulling down,
Normal force N pushing up,
and friction force Nμ pushing towards the center.
Sum of forces in the y direction:
∑F = ma
N − mg = 0
N = mg
Sum of forces in the centripetal direction:
∑F = ma
Nμ = m v²/r
Substitute and simplify:
mgμ = m v²/r
gμ = v²/r
Write v in terms of ω and solve for r:
gμ = ω²r
r = gμ/ω²
Plug in values:
r = (10 m/s²) (0.5) / (2.5 rad/s)²
r = 0.8 m
Answer:
Explanation:
The capacitive reactance is given by:
Now, The inductive reactance is given by:
By the ohm´s law, the electrical impedance is:
So
The total impedance is:
(*)
Where X is the total reactance given by:
Let´s calculate the real part of Z using (*):
Finally the angle between the current and the voltage is equal to the impedance angle:
