Which measurement is a vector?
Andreas93 [3]
To measure a vector is to characterize both its direction (in one form or another) and a value (usually, a number). For example, velocity of a car moving on the road is a vector and, to measure it, we have to specify its direction (e.g. North or at angle 20 degrees from the North) and value (e.g. 40 m/sec).

Place the following in order of increasing IE1
lyudmila [28]

Answer:

A) As < N < F

Explanation:

Ionization energy refers to the minimum amount of energy required to remove an electron from a gaseous atom r in.

The genera trend of IE, is that it increases across the period from left to right and decrease down the group in a periodic table.

As belongs to period 4, this means it as the lowest ionization energy.

Nitrogen and Florine belong to the same period however Florine has a higher ionization energy.

In order of increasing IE;

As < N < F

Solids have:<br> fixed shape<br> O A and B<br> fixed size<br> neither A nor B
Lemur [1.5K]

<u>Answer:</u>

<em>B. A and B</em>

<em></em>

<u>Explanation:</u>

1. Solids have a definite volume, definite size and definite shape

2. The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.

3. Melting point is the temperature at which solid changes into a liquid.

4. When a solid is heated to the melting point the intermolecular forces are overcome by the energy and the molecules present in it moves from its fixed position to take its liquid state which is called as melting.
