Answer : Y > W > X > Z

Explanation :

The electrostatic force is given by :

F=k\dfrac{q_1q_2}{d^2}

k is the electrostatic constant

q₁ and q₂ are charges

d is the distance between them

We will calculate forces one by one :

F=k\dfrac{q.q}{d^2}=\dfrac{kq^2}{d^2}

W=k\dfrac{q.2q}{d^2}=\dfrac{2kq^2}{d^2}=2F

X=k\dfrac{q.q}{(2d)^2}=\dfrac{kq^2}{4d^2}=\dfrac{F}{4}

Y=k\dfrac{3q.q}{d^2}=\dfrac{3kq^2}{d^2}=3F

Z=k\dfrac{q.q}{(3d)^2}=\dfrac{kq^2}{9d^2}=\dfrac{F}{9}

So, the force from greatest to least will be :

Y > W > X > Z

So, the correct option is (B)

Unpolarized light whose intensity is 1.46 W/m2 is incident on the polarizer in the drawing. (a) What is the intensity of the lig
Serhud [2]

Answer:

0.73 W/m²

0.2522 W/m²

Explanation:

I_0 = Unpolarized light = 1.46 W/m²

\theta = Analyzer angle = 54°

Light through first filter

I_1=\frac{I_0}{2}\\\Rightarrow I_1=\frac{1.46}{2}\\\Rightarrow I_1=0.73\ W/m^2

The intensity of the light leaving the polarizer is 0.73 W/m²

After passing through analyzer

I=I_1cos^2\theta\\\Rightarrow I=0.73\times cos^2(54)\\\Rightarrow I=0.2522\ W/m^2

The intensity of the light that reaches the photocell is 0.2522 W/m²

Differences between plastic and metal​
beks73 [17]

Answer:

Differences are listed below:

Explanation:

Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.

Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.

Machinability: Plastic are much more easier to cut through than metal.

Product life: The life span for plastic is longer than of the metals in many applications.

Cost: The cost of plastic raw materials is appreciably less than of the metals.

Heat: Plastic are less heat resistive than metals.

Ultraviolet light can degrade the plastics soon.

Strength: Metal provides more strength than the plastic.
