Answer:
Explanation:
Intensity of unpolarized light = I(o)
Intensity of light after first polarization by polarizer A. = I(o)/2
Angle between A and B = 120 degree.
Intensity of light after second polarization = I Cos² θ
= I(o) /2 x cos²120 = I(o) /8 .
Angle between B and C is 70 degree
Intensity of light after third polarization =
I(o)/8 x Cos² 70 = 0.1156 x I (o) /8 =
Required ratio =.01445
Work done in compressing spring = 40.833
It simply needs a three-inch compression by applying a compressive force to a 15-inch long spring. we know that F(x)=kx. To act in displacement X and the poles' values cannot be substituted. Consequently, there will be 4. The spring constant K is therefore equal to 5, so. Three fit within this slot. We consequently derive the compressing spring constant K from this. , which is 5, 3. Now change this formula to include the value of the compressing spring constant. Four f will therefore equal 5.3 x and vice versa. Integration of four factors equals W.
In order to ensure the limit and further all of this, we currently have the range 0–7. Thus, this compressing spring task is completed. W is equal to 40.833

Work = force * distance.
We must produce twice as much energy as we are lifting the weight twice as high.
But we are not increasing the force so we must increase the length of the ramp ( distance ) instead.
The new length will be twice as great as the previous length.
So 8 metres is required.
25 kg * 8 m = work = 100 kg * 2 m
A reflecting will have a mirror on the bottom where the light will bounce off a retracting uses lenses that focus the light
