Answer:

c. Corriente eléctrica.

Step-by-step explanation:

<em>Cuando un campo magnético cambia en intensidad y alrededor de esa región se encuentra un conductor eléctrico, tal cambio en la intensidad induce una </em><u><em>corriente eléctrica</em></u><em> en ese conductor.</em> Ese es el principio de los generadores de corriente o generadores eléctricos.  

Este principio es conocido como la <em>Ley de Faraday de Inducción Electromagnética, </em>estudiada por Michael Faraday (1791-1867) y es parte fundamental de la Teoría Electromagnética.

En líneas generales, este principio de Faraday y el hecho de que la variación de un campo eléctrico genere un campo magnético, principio descubierto por Hans Christian Oersted (1777-1851), y que sostiene que <em>la variación de la corriente eléctrica en un conductor genere alrededor de éste un campo magnético</em> (principio de los electroimanes), <em>son complementarios</em> y podría decirse que son los pilares de la Teoría Clásica del Electromagnetismo, cuyas leyes están descritas matemáticamente en las <em>ecuaciones de Maxwell</em>, llamadas así por James Clerk Maxwell (1831-1879), quien se basó principalmente en los resultados de Faraday para formularlas.

Answer:

840

Step-by-step explanation:

The 3 by 3 grid below shows nine 1 cm x 1 cm squares and uses 24cm of wire

24 cm of wire

is  3 (3 + 1)  + 3(3 + 1)

= 3 x 4 + 3 x 4

=  12 + 12

= 24 cm

length of wire is required for a similar 20 by 20 grid

= 20(20 + 1)  + 20(20 + 1)

= 20 x 21 + 20 x 21

= 420  + 420

= 840  cm

Expand.<br> Your answer should be a polynomial in standard form.<br> (9+ m)(-m +9)=
valina [46]

Answer: -1m²+81

Step-by-step explanation:

correct standard form means that the terms are ordered from biggest exponent to lowest exponent.The leading coefficient is the coefficient

of the first term in a polynomial in standard form.

FoR example, (9+ m) (-m+9) = *(m+9) (-m+9) *m(-m+9) +9 (-m+9)* -1.mm+9m +9(-m+9) * -1m² +9m +9(-m+9) *-1m²+9m- 9m +81

answer -1m²+81

Can someone please help me with this and tell me the points?
Svetllana [295]

Answer:

Graph: Refer to attached image

Solution: (-5,-3)

Step-by-step explanation:

First graph to two equations.

Refer to the image attached to see what the equations would look like when graphed.

Wherever they intersect is the solution.

They intersect at (-5,-3) therefore (-5,-3) is the solution to the system of equations
