Answer:

D) An electromagnet with 20 coils.

Explanation:

An electromagnet will produce magnetic field on its axis given by the equation

B = \mu_0 ni

here we know that

n = number of turns per unit length

i = current in the coil

Now if we need to increase the magnetic field strength of the electromagnet then we can increase its turns

so we will have

D) An electromagnet with 20 coils.

D: An electromagnet with 20 coils.

That is because the more coils of the wire, the stronger the electromagnet is.

The inner planets are relatively small bodies composed mostly of rock and metals. Why did they develop this way instead of becom
sleet_krkn [62]

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K. In the inner solar system, only substances with very high melting points would have remained solid. All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets. The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets. These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe

Tanzania [10]

Answer:

I think it is D

Explanation:

the Bohr model says that electrons whizz around the atomic nucleus in the same way that the earth goes around the sun - but rather than being bound by gravity, it is bound by electromagnetic forces.
