Answer:
A) I = Io 0.578, B) he light that leaves the polarized is completely polarized, being perpendicular to the axis of the second filter
Explanation:
A) Light passing through a polarizer must comply with the / bad law
I = Io cos2 tea
Where is at the angle of the polarizer and incident light
I = Io cos2 45
I = Io 0.578
Therefore the beam intensity is 0.578 of the incident intensity
.B) the light that leaves the polarized is completely polarized, being perpendicular to the axis of the second filter
A mode that uses sliding friction would be sledding. :)
450 J / 3 s = 150 J/s = 150 watts.
Answer:r=242ohms
Explanation:
Power(p)=50w
Volt(v)=110v
Resistance(r)=?
Power(p)=((volt)^2)/(resistance(r))
50=110^2/r
Cross product
50xr=110^2
50r=12100
r=12100/50
r=242ohms
