Answer: Your correct main answer is a submarine

Explanation:

Submarines are usually used for underwater warfare, and naval submarines are equipped with torpedoes, missiles, and high-powered nuclear weapons. The use of these along with their advanced tracking system helps to target ships and boats from below as well as other enemies. They can also work on targets that are on land.

Answer: <u><em>Sonar</em></u> is used mainly in submarines that remain underwater

Explanation:

Sound travels through water a lot faster than through air. Sonar is used in submarines because having a window in the depths of the ocean would not be practical because of the amount of light down there and the pressure down there is a lot more than at sea level.

If I was given more context I'm sure it could give a more helpful answer.

<h2>ANSWER:</h2>
  • <u>The north pole</u>

  • The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

Two representative elements are in the same period of the periodic table. Which statement correctly describes the atoms of the t
sveticcg [70]

1) They have valence electrons in the same energy level.

2) Helium atoms have 2 valence electrons, while atoms of the other elements in the group all have 8 valence electrons.

3) cesium (Cs)

4) There are two electrons in the first energy level and seven electrons in the second energy level.

In the periodic table, elements are arranged in order of increasing atomic number into groups and periods.

In the periodic table, we have an arrangement of atoms based on their respective groups and periods.

If I pick two representative elements in the same period, their number of valence electrons will differ by 1 but they will all be accommodated in the same energy level.

Helium is the first member of group 18. Unlike the other members of the group, its first shell is also its valence shell. It has two and not eight valence electrons like other members of the group.

The electronic configuration of Ca is [Ar] 4s², that of Li is [He] 2s1, that of Cs is [Xe] 6s1, that of Br is [Ar] 4s² 3d¹⁰ 4p⁵ and that of oxygen is [He] 2s² 2p⁴.

We can see that only Cs has  valence electrons in higher energy orbitals than those of Ca.

Lastly, Fluorine is in group 17. There are nine electrons in this atoms. They arranged in such a way that there are two electrons in the first shell and seven electrons in the second shell.

yuradex [85]

Answer:

2\Omega

Explanation:

(Assuming the cell in the circuit has 0 internal resistance)

Ohm's Law is given as:

V=IR

Voltage is Current multiplied by Resistance.

We can rearrange this formula to give us:

R=\frac{V}{I}

Now we can plug in our values

R=\frac{6}{3}=2\Omega
