Answer:

The magnetic north and south poles of Earth are interchanged.

Explanation:

Earth acts as a huge bar magnet due to the presence of iron and nickel in its core. The magnetic field surrounding Earth is known as magnetosphere which constantly protects from solar wind. Auroras are visible in the sky when charged particles from the sun interact with the magnetic field of the earth especially near the poles where strength of the magnetic field is maximum.  

Over the years, the magnetic field might weaken as it is continuously repelling the charged particles from the Sun. As a consequence, the poles of this magnetic field might reverse.

Thus, changes in Earth's magnetic field can reverse the poles.

The only statement that makes sense as to which one describes an effect of changes in Earth's magnetic field is the first one - <span>Southern lights are seen at high altitude places like Alaska.
Normally, Southern lights are seen around the South Pole, which means that it is quite odd for them to be seen in Alaska, which is near the North Pole.</span>

A 1200 kg car accelerates from 13 m/s to 17 m/s. find the change in momentum of the car.
mixas84 [53]
P=4800kgm/s
As
p=mΔv
where p is momentum, m is mass and v is velocity
Given values is
m =1200kg
Δv= 17m/s-13m/s=4m/s
Now
p=mΔv
p=(1200kg)*(4m/s)
p=4800kgm/s

miss Akunina [59]

Answer:

2. a region about the nucleus in which an electron of specified energy will probably be found

Explanation:

With quantum mechanics we can find the wave function that describes the movement of the particles, the interpretation of this wave function is through the probability density (φ* φ).

This probabilistic interpretation of the energies, position and amounts of motion electrons allow us to find the region around the nucleus where an electron of specific energy can be found with a given probability.

The correct answer is 2
