The expression that represents the difference of squares for this situation is x^2-c^2

Given the generic x by x grid has c blocks moved to create an (x-c) by (x+c) grid, to get the difference of two squares, we will take the product of the expressions as shown:

=(x-c)(x+c)\\=x^2+xc-xc-c^2\\=x^2 -0-c^2\\=x^2-c^2

Hence the expression that represents the difference of squares for this situation is x^2-c^2

The periodic table is arranged by various patterns. Is there a pattern with regard to ionic charge? In three to five sentences,
Flura [38]

Ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.

Ionic charge is the electrical charge of an ion formed when when an atom gains or losses electron.

Metals form ionic charge (cation) by the loss of electron while non-metal form ionic charge (anion) by the gain of electron.

  • This ionic charge increases across the group and consequently, results in a decrease of ionic radius.
  • When a positive ion (cation) transfers electron to the negative ion (anion) an Ionic bond will be formed.

<u>For example</u>;

  • ionic charge of group 1 elements = +1
  • ionic charge of group 2 elements = + 2
  • ionic charge of group 3 elements = + 3
  • ionic charge of group 4 elements (carbon group) = -4 or +4, (<em>they don't usually form ions</em>)
  • ionic charge of group 5 elements = -5
  • ionic charge of group 6 elements = -6
  • ionic charge of group 7 elements = -7

Thus, we can conclude that ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.

The vibration in a plucked guitar string travels at a speed of 410 meters per second. How far, in centimeters will the vibration
ipn [44]

Answer:

16.4 cm/0.4 ms

Explanation:

1: We know that the travel rate is 410 meters per second. We want to find a way in which we can cancel meters or seconds, and we can do that by multiplying 410m/1s with 100 cm/1m.

\frac{410 m}{1s} * \frac{100cm}{1m}

2. Now we want to get rid of that s, seconds, and we do so by multiplying prior fractions by 1s/1000ms.

\frac{410 m}{1s} * \frac{100cm}{1m} * \frac{1s}{1000ms} \\

3. Now we can diagnollay cross out m, and s. Leaving us with cm on top, and ms on the bottom. Which is what we want because we are calculating how many cm are for every .04 ms.

4: After that, you can multiply 410 and 100, to get 4,100. Whih leaves you with 4,100cm over 1000ms. Simplifying this, gives you 41, but that is NOT your answer. 41 cm, is for every ms, NOT every .04

5. Hence, you multiply 41 by .04 and get 16.4cm/.04ms.

topjm [15]

A greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.

<h3>What is kinetic energy?</h3>

It should be noted that kinetic energy simply means a form of energy of an object due to motion.

In this case, a greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.
