Magnetic field lines don't start or stop anywhere, they always make closed loops and will continue inside a magnetic material (though sometimes they are not drawn this way). Magnetic field lines naturally bunch together in regions where the magnetic field is the strongest. This means that the density of field lines indicates the strength of the field.
Magnetic field lines never cross.

In other words, is called “field lines”

For a satellite already in perfect orbit around the Earth, what would happen if: - the satellite's speed is reduced? - the satel
Maksim231197 [3]

Answer:

Answer

Explanation:

If the satellite is in perfect orbit around the earth then gravitational pull of the earth on the satellite and moving forward satellite is in perfect balance i.e gravitational pull does not effect the orbit as the velocity of the satellite is good enough to counter the gravitational pull of the earth and inertia makes the satellite move forward with greater velocity, but when its velocity is suddenly reduced, the gravitational pull will counter on the orbiting satellite and it will crash onto the earth.

This is same as in well of death when motorist moves in circular motion inside the well with centripetal and centrifugal forces balanced, suddenly crashes on the ground when velocity of the motorist is not enough to balance forces.

the satellite's mass has no affect on its orbit around the earth rather the mass of the earth is only affecting factor .

Un motor realiza un trabajo de 5000 j en 20 s a) ¿ cual es la potencia del motor ?B)¿en cuanto tiempo desarollan el mismo trabaj
zimovet [89]

Answer:

a. Potencia = 250 Watts

b. Tiempo = 333.33 segundos

Explanation:

Dados los siguientes datos;

Energía = 5000 Joules

Tiempo = 20 segundos.

Para encontrar el poder;

Poder = energía/tiempo

Potencia = 5000/20

Potencia = 250 Watts

B. ¿Para saber cuánto tarda una máquina en realizar el mismo trabajo;

Dado: potencia = 15 W

Tiempo = energía/poder

Tiempo = 5000/15

Tiempo = 333.33 segundos

Calculate the total mass of these letters in grams (mxe=131.29amu)
Lady_Fox [76]
We know avogadro's number = 6.023 x 10²³
1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴grams
<span>Now, to convert amu to grams,
 131.29 amu = 131.29 x 1.66 x 10</span>⁻²⁴grams
<span>= 2.18 x 10</span>⁻²²<span> grams is the answer</span>
