Answer:
2.36 x 10^6 Hz
Explanation:
We know ;,
Iamp = 1.8mA
L = 0.45mH
VL = 12V
VL = IwL
VL = I x 2π x f x L
f = VL / (I x 2π x L)
f = 12 V/ (1.8mA x 2π x 0.45mH)
f = 12/(1.8x10^-3 x 2π x 0.45 x 10^-3)
f = 2.36 x 10^6 Hz
F = 130 revs/min = 130/60 revs/s = 13/6 revs/s
t = 31s
wi = 2πf = 2π × 13/6 = 13π/3 rads/s
wf = 0 rads/s = wi + at
a = -wi/t = -13π/3 × 1/31 = -13π/93 rads/s²
wf² - wi² = 2a∅
-169π²/9 rads²/s² = 2 × -13π/93 rads/s² × ∅
∅ = 1209π/18 rads
n = ∅/2π = (1209π/18)/(2π) = 1209/36 ≈ 33.5833 revolutions.
Answer:
The displacement of the spring due to weight is 0.043 m
Explanation:
Given :
Mass
Kg
Spring constant 
According to the hooke's law,

Where
force,
displacement
Here,
(
)
N
Now for finding displacement,

Here minus sign only represent the direction so we take magnitude of it.

m
Therefore, the displacement of the spring due to weight is 0.043 m
You finna have to pay me lol what it look like though and i’ll see if it’s worth it make some
It can hurt and harm the body on many different and levels
