Answer:
the rate of precession is 0.041 rad/s
Step-by-step explanation:
given information:
radius, R = 50 cm= 0.5 m
disk length, d = 11 cm, r = 5.5 cm = 0.055
angle, θ = 30°
angular velocity of the disk, ω = 1000 rev/min = 1000 2π/60 =
rate precession, Ω
Ω = m g r / I ω
where
m = mass
g = gravitational force
r = the radius of the center disk
I = inertia
ω = angular veocity
I =
Ω = (m g r )/ ( ω)
= 2 g r / ( ω)
= 2 x 9.8 x 0.055 / ( 104.7)
= 0.041 rad/s
Just divide 78 billion by 78 thousand
Answer: 5n-6=39;n=9
Step-by-step explanation:
The product of: indicates multiplication
A number: indicates you need a variable (n)
And five: indicates what your multiplying (5)
Decreased by six: indicate your subtracting 6
Is thirty nine: indicates your answer is 39
Now solve using inverse operations
5n-6=39
<u> +6 +6</u>
<u>5n</u>=<u>45</u>
5 5
n=9
