Answer:
if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
Explanation:
The incident light is generally random, that is, it does not have a polarization plane, when the first polarized stops by half, this already polarized light arrives at the second polarizer and the causticity passes
I = I₀ cos² θ
therefore if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
Answer:
F = 20.07 μN
Explanation:
given,
intensity of sunlight = 667 W/m²
area of surface = 9.03 m²
speed of light = 3 x 10⁸ m/s
force = ?
we know
force =
force =
F = 20.07 x 10⁻⁶ N
F = 20.07 μN
The output voltage is 10 times the input voltage.
So the output coil has 10 times as many turns as the input coil has.
That's how transformers work.
Complicated, huh !
10 times 1,000 turns = <em>10,000 turns</em>
Answer:
Explanation:
<u>Relation between stress and Force:</u>
<u>Relation between stress and strain:</u>
Young's modulus is defined by the ratio of longitudinal stress σ , to the longitudinal strain ε:
So:
9.0, might be to late but someone in the future might need it.
