igneous rock determined 25 million year old plate movement transported 100,000 meters. How fast is plate moving?
dedylja [7]

Answer:

0.004 m/yr.

Explanation:

Hello!

In this case, since the velocity of any object is computed by dividing the travelled distance by the elapsed time, we obtain:

V=\frac{distance}{time}\\\\V=\frac{100,000m}{25,000,000yr}\\\\V=0.004m/yr

It means that the plate moves 0.004 m every year.

Best regards!

What are valence electrons?
Ksivusya [100]

Answer:

D

Explanation:

The simple answer is the electrons in the outermost energy level.

Hydrogen has 1 electron in the outermost energy level.

Magnesium has 2 so this tells you that magnesium has a charge of 2

Oxygen has 6  oxygen has a charge of - 2

Fluorine has 7

For most elements, the electrons in the most outer ring determine the valence of the element.

Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.

Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
