Answer:
- the speed of a person "stuck" to the wall is 14.8 m/s
- the normal force of the wall on a rider of m=54kg is 1851 N
- the minimum coefficient of friction needed between the wall and the person is 0.29
Explanation:
Given information:
the radius of the cylindrical room, R = 6.4 m
the room spin with frequency, ω = 22.1 rev/minutes = 22.1 
= 2.31 rad/s
mass of rider, m = 54 kg
the speed of a person "stuck" to the wall
v = ω R
= 2.31 x 6.4
= 14.8 m/s
the normal force of the wall on a rider
F = m a
a = ω^2 R
= 
R
= 
F = 
= 
= 1851 N
the minimum coefficient of friction needed between the wall and the person
F(friction) = μ N
W = μ N
m g = μ
g = μ
μ = 
= 
= 0.29
The current is
(120v) / (the resistance of the stove in ohms) .
The unit of the current is Amperes.
Because it's literally impossible to tell exactly where something that size is
located at any particular time.
And that's NOT because it's so small that we can't see it. It's because any
material object behaves as if it's made of waves, and the smaller the object is,
the more the size of its waves get to be like the same size as the object.
When you get down to things the size of subatomic particles, it doesn't make
sense any more to try and talk about where the particle actually "is", and we only
talk about the waves that define it, and how the waves all combine to become a
cloud of <em><u>probability</u></em> of where the particle is.
I know it sounds weird. But that's the way it is. Sorry.
1. Eat a balanced diet and regular exercise. This is the best way because eating right and exercising are is more beneficial than just exercising.
