What is the maximum resultant intensity in terms of the intensity of the initial unpolarized incoming light io?

Dennis_Churaev [7]

The unpolarized light becomes less intense. When unpolarized light is run through a polarizer, its intensity is diminished by a factor of ½.

<h3>Unpolarized light:</h3>

Unpolarized light is diminished by a factor of ½ when it travels through a polarizer. Cos 2θ averages out across all angles to be ½ in size. I transmitted = I₀ and ½ I₀ at all angles The unpolarized light's intensity decreases to zero.

The light-producing atoms on the heated filament's surface behave independently of one another. Each of these emissions can be roughly represented as a brief "wave train" lasting between approximately 109 and 108 seconds. These wave trains, each with its unique polarization direction, are superimposed to form the electromagnetic wave that is coming from the filament.

Unpolarized light is produced by all common light sources, including the Sun, incandescent and fluorescent lighting, and flames.

Pulling a wheel with a string? A bicycle wheel is mounted on a fixed, frictionless axle, with a light string wound around its ri

m_a_m_a [10]

A)♣ the string being pulled,
the angular speed is: w1=w0 +w’*t, hence t=(w1-w0)/w’; 
the angular path is: b=w0*t+0.5*w’*t^2, where angular acceleration 
w’=T/J, torq T=F*r, and b*r=L; 
♦ thus b=w0*(w1-w0)/w’ +0.5*w’*((w1-w0)/w’)^2 = 
= (w1-w0)*(w0 +0.5w1 -0.5w0)/w’ =0.5*(w1^2 –w0^2)/w’; 
♠ and b=L/r =0.5*(w1^2 –w0^2)/(F*r/J); 
2(F*r/J)*L/r =w1^2 –w0^2, hence 
w1^2=2F*L/J +w0^2; 
b)♣ the power is P=F*(w0*r);

Potential energy can be converted into kinetic energy, a good example of this is when a pole-vaulter bends the pole during a lea

lesantik [10]

Answer:

The pole stores elastic potential energy when the pole is bent because its shape is change from its natural shape and it will want to go back to its original form, just like a spring or stretched elastic material.

The system of two rods will lie on the table as show in the figure

The center of first rod will lie exactly at the edge of first rod and then the center of mass of two combined rods will lie at the edge of the table.

So now the whole system will rest on the rod and it will not tipping off.

Since both rods are identical so we can say that the system will have its center of mass at the mid point on the line joining the two centers

So the value of x will be at mid point of line joining the two points on rod
