Answer:

Explanation:

If no one can see it because the lights were out. Did the flea really jump?

What do you want here?

Max height (2.2sin21)²/ 2(9.8) = 3.2 cm

Time of flight 2(2.2sin21)/ (9.8) = 0.16 s

distance of flight (2.2cos21)(0.16) = 33 cm

A clear sheet of polaroid is placed on top of a similar sheet so that their polarizing axes make an angle of 30° with each other
xxMikexx [17]

Answer:

\dfrac{I}{I_0}=\dfrac{3}{8}

Explanation:

Given that

Angle ,θ = 30°

From Malus law,Intensity given as

I=\dfrac{I_0}{2}cos^2\theta

Io=Intensity of unpolarized light

I=Intensity of emerging light

Now by putting the value of angle

I=\dfrac{I_0}{2}cos^2\theta

I=\dfrac{I_0}{2}cos^230^{\circ}

We know that

cos30^{\circ}=\dfrac{\sqrt{3}}{2}

I=\dfrac{I_0}{2}\times \dfrac{3}{4}

\dfrac{I}{I_0}=\dfrac{3}{8}

Therefore ratio will be \dfrac{3}{8}
