A physical change in something doesn't change what the it is. For example, if you break glass, it will still be glass. In a chemical change where there is a chemical reaction, a new thing is formed and energy is either given off or absorbed. For example, when you burn a log. The carbon in the log is reacting to the oxygen to create ashe and smoke

What is described by the terms body-centered cubic and face-centered cubic?
Montano1993 [528]
In physical chemistry, the terms body-centered cubic  (BCC) and face-centered cubic (FCC) refer to the cubic crystal system of a solid. Each solid is made up simple building blocks called lattice units. There are different layouts of a lattice unit.

It is better understood using 3-D models shown in the picture. A BCC unit cell has one lattice point in the center, together with eight corner atoms which represents 1/8 of an atom. Therefore, there are 1+ 8(1/8) = 2 atoms in a BCC unit cell. On the other hand, a FCC unit cell is composed of half of an atom in each of its faces and 1/8 of an atom in its corners. Therefore, there are (1/2)6 + (1/8)8 = 4 atoms in a FCC unit cell.

During an earthquake you should.
White raven [17]

Well, you should TAKE COVER UNDER A STUDY DESK, TABLE OR AGAINST AN INSIDE WALL. Which is C. This is because, doing this protects you from the falling objects. If you do A or B, you will probably get crushed by falling objects because you are exposed. Hope I helped.

Many flashlights are powered by a stack of batteries that are slid into the end of the flashlight one after another. Suppose you
Basile [38]

Answer:

The current through the bulb when the flashlight is turned on is 0.55 A.

Explanation:

Given that,

You have a flashlight that takes four ideal 1.5 V batteries, voltage of the flashlight, V = 6 V

The resistance of bulb, R = 11 ohms

We need to find the current through the bulb when the flashlight is turned on. As per Ohms's law :

V = IR

I=\dfrac{V}{R}\\\\I=\dfrac{6\ V}{11\ \Omega}\\\\I=0.55\ A

So, the current through the bulb when the flashlight is turned on is 0.55 A. Hence, this is the required solution.
