The Force on the left hand pole, F' = 0.167N
<h3>What is the force on the left hand pole?</h3>
Force is an agent which produces a change in the motion or state of an object.
Force is a vector quantity.
The general force is calculated as follows:
F = mg/sinθ
m = 17.1 g = 0.0171 kg
g = 9.81 m/s²
θ = 45°
F = 0.0171 * 9.81/sin45
F = 0.237 N
Force on the left hand pole, F' = Fcosθ
F' = 0.237 * cos 45
F' = 0.167N
In conclusion, the force on the left hand pole is the horizontal component of force.

Answer:
(a) the angular velocity at θ1 is 11.64 rad/s
(b) the angular acceleration is 0.12 rad/
(c) the angular position was the disk initially at rest is - 428.27 rad
Explanation:
Given information :
θ1 = 16 rad
θ2 = 76 rad
ω2 = 11 rad/s
t = 5.3 s
(a) The angular velocity at θ1
First, we use the angular motion equation for constant acceleration
Δθ = (ω1+ω2)t/2
θ2 - θ1 = (ω1+ω2)t/2
ω1 + ω2 = 2 (θ2 - θ1) / t
ω1 = (2 (θ2 - θ1) / t ) - ω2
      = (2 (76-16) / 5.3) - 11
      = 11.64 rad/s
(b) the angular acceleration
ω2 = ω1 + α t
α t = ω2 - ω1
α = (ω2 - ω1)/t
   = (11.64 - 11) / 5.3
   = 0.12 rad/
(c) the angular position was the disk initially at rest, θ0
at rest ω0 = 0
ω2^2 = ω01  t + 2 α Δθ
2 α Δθ = ω2^2 
θ2 - θ0 = ω2^2  /  2 α
θ0 = θ2 -  (ω2^2) / 2 α
   = 76 - ( / 2 x 0.12
/ 2 x 0.12
   = 76 - 504.16
   = - 428.27 rad
 
        
             
        
        
        
Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s
We have to find final velocity.
The equation we use is 
Final velocity=initial velocity+acceleration x time 
Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s
We would round this to:
Vf (final velocity)=2.7m/s
        
             
        
        
        
If you cannot get a chair to move across the floor, it is because static friction opposes your push. When you say static or kinetic friction the two object that facing each other are opposing each other. That's why you're having a hard time pushing the chair.
        
             
        
        
        
Answer:
75.5g
Explanation:
From the ionic equation, we can write 

next we find the number of charge 
Note Q=it
for i=8.5A, t=3.75 to secs 3.75*60*60=13500secs
hence 

Since one faraday represent one mole of electron which equal 96500C
Hence the number of mole produced by 114750C is 
114750/96500=1.2mol
The mass of copper produced is 

Hence the amount of copper produced is 75.5g
