We can say that the components of ANY light oscillate perpendicular
to the direction of propagation ... left and right, up and down, upper left
and lower right, upper right and lower left, etc. ... any direction ACROSS
the direction of propagation, just not forward and backward.
If the light is polarized, then the Ɛ-field (electrostatic) component of
the wave can only oscillate in the polarized direction ... say, left and
right across the direction of propagation. (The magnetic component
is always perpendicular to the electrostatic component. So if the
polarizer is left/right, then the magnetic component is up/down.)
Any light that doesn't oscillate in the direction selected by the polarizer
gets absorbed in the polarizer, and doesn't come out the other side.
That's why when you pass light through a polarizer, it comes out dimmer
than it went in.
LASER light is always naturally polarized before it comes out of the diode
or whatever is generating it. That's another advantage of laser light.
Assuming you are supposed to write each conversion in scientific notation:
(2) 1 m = 100 cm, so
(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m
(3) 1 km = 1,000 m, so
(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m
(4) 1 m = 1,000 mm = 10³ mm, so
(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm
(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so
(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m
(6) 1 g = 1,000,000 µg = 10⁶ µg, so
(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g
Yes. As bits of paper comes in electric field of charged comb, it attracts paper towards itself by a force called it's 'Electric force" & that process of flow of electrons is called "Electrical Conduction"
In short, Your Answer would be "True"
Hope this helps!
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Below are the choices that can be found from other sources:
A. The marlin has more momentum.
<span>B. The salmon has more momentum. </span>
<span>C. Both have the same momentum. </span>
<span>D. Both have no momentum.
</span>
Velocity is speed. Momentum is the product of velocity and mass. Because the Marlin has a much greater mass that means that it's momentum would also be greater.
<span>Lets look at this. momentum = mass x velocity </span>
<span>lets say that velocity for both fish is at 2 meters per second </span>
<span>Marlin : momentum = 500 x 2 = 1000 </span>
<span>Salmon : momentum = 20 x 2 = 40 </span>
<span>Therefore the answer is A</span>
