Answer:

the element must be in the fifth, sixth, or seventh energy shells.

Explanation:

Because the first ionization energy is less than calcium's, the element must be larger and in the next energy shell. Calcium is in the fourth energy shell, so the element must be in the fifth, sixth, or seventh energy shells.

The strength of a magnet can be incresed by what in science
adoni [48]
Answer:

Take the magnet which has lost its power and stroke it with the stronger magnet. Linear strokes in a single direction will realign the electrons within the magnet, which will help its strength to increase. Stroke the magnet for around 15 minutes, and check to see if the strength has returned.

I hope this helped! :)

Two skydivers of different masses jump from a plane
vampirchik [111]

The relationship between the net force of both sky divers is that; the net force for both skydivers is the same.

<h3>What is the net force experienced? </h3>

We are told that two skydivers of different masses are jumping out of an airplane. Now, at some point, both skydivers will slow down to the point at where they reach constant velocity.

Due to the fact that the velocity for both sky divers is constant, it means that no acceleration will occur and as such, the net force on each sky diver is zero.

Thus, we conclude that the net force for both skydivers is the same.
