Answer:
Polarization is the attribute that a wave’s oscillations have a definite direction relative to the direction of propagation of the wave. (This is not the same type of polarization as that discussed for the separation of charges.) Waves having such a direction are said to be polarized. For an EM wave, we define the direction of polarization to be the direction parallel to the electric field. Thus we can think of the electric field arrows as showing the direction of polarization, as in Figure 2.
To examine this further, consider the transverse waves in the ropes shown in Figure 3. The oscillations in one rope are in a vertical plane and are said to be vertically polarized. Those in the other rope are in a horizontal plane and are horizontally polarized. If a vertical slit is placed on the first rope, the waves pass through. However, a vertical slit blocks the horizontally polarized waves. For EM waves, the direction of the electric field is analogous to the disturbances on the ropes.
Explanation:
<h2>Answer</h2>
1 V = 1 kg m2 s−² C
1 V = 1 kg m2 s−³ A−1
(one kilogram meter squared per second cubed per ampere)
<h2>Explanation</h2>
<em>The work required to move an electric charge of one coulomb through an electrical potential difference of one volt,</em>
<h2> Volts = Joules / Coulombs</h2><h2 />
Joules = Newton x metre
Volts = Nm / coulombs
Newton = kg x metre / second ²
Volts = kg x metre / second ² coulombs
Volt in terms of meters (m), seconds (s), kilograms (kg), and coulombs (c)
<h3>For further:</h3>
Coulomb = Amp * second
Volts = kg x metre / second ³ Amp
<h2 />
Answer:
C)
Explanation:
The most common way of measuring homelessness is through so-called 'point-in-time' estimates of people who are sleeping in shelters or on the streets. These are figures that are intended to reflect the number of people who are homeless 'on any given night'.
Answer:
Inertia; Newton's First Law
Explanation:
When you hit you're breaks, the force you feel that pulls you forward is due to inertia.
Newton's first law says that "every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force." The question is a perfect example of this.
Answer:
Their discoveries both had to do with the relationship of the earth to the sun and universe. That the earth wasn't the centre of the universe and that the sun didn't rotate round the earth but rather the other way.
Explanation:
Nicolaus Corpenicius (19 February 1473 - 24 May 1543) was a scientist, astronomer and renaissance era polymath, who was fascinated with stars. He was the first to formulate a model of the universe that had the sun at the centre of the universe instead of the earth. It was such a groundbreaking discovery. Corpenicus is often referred to as the father of Modern Astronomy.
Galileo Galilie (15 February 1564- 8 January 1642) was an italian physics philosopher who was famous for his discovery that the earth rotated round the sun. it was a big deal in his time, because, the prevailing thought in his day, was that the earth was the centre of the universe and the sun rotated round the verse. Though Corpenicus was the first to discover and publish it. Further discoveries and inventions by Galileo proved corpenicus as true.
