The answer is free flowing
electrons can move about freely, creating an electric current, because they are not bound to atoms

Answer:

Because the electrons are "free" (some of them, of course)

This means that they are not bounded to a particular molecule or particle, this means that they can "flow" along all the material, and the rules that they respect are the ones of electromagnetism (for example an electron can't flow freely, it must follow a "pattern" this is way wen you have electrical current all the electrons are flowing in the same direction)

Another answer can be: Because electrons are charged, of course, if the electrons weren't charged the electromagnetic fields would not affect them, and even if they flowed, there will not be ani electric charge.

So you need two things in order to have current, you need a charged object, and this object must be free so it can flow along with the material.

The correct answer to this open question is the following.

“If we remembered everything, we should on most occasions be as ill off as if we remembered nothing.” William James.

What Willia James tried to share with this quote was that people have to forget and live. That it is not a good thing to carry the burdens of life, generating resentments all your life. Whatever happened one year ago or ten years ago, it's in the past. To be happy you have to free of those burdens that come from time to time and produce bad feelings, just by reminding you what happened or who made what to who.

So for me is a good quote to remind ourselves to forgive and forget, and keep on living a happy life without resentments.

The algorithm below simulates rolling a regular 6-sided die twice. Consider the goal of determining if the sum of the values of
FrozenT [24]

Algorithms are used to simulate real programs.

The true conditions of the algorithm are:

  • <em>(a) If the value found in step 6 is 10, 20, 30, 40, 50 or 60 then the sum is even </em>
  • <em>(b) If the last digit of the value found in step 6 is 5, then the sum is odd</em>

First, we analyze the algorithm.

Assume the outcomes of the two rolls are x and y

<u>Step 4: Calculate sum</u>

Sum = x + y

<u>Step 5: Multiply Sum by 10</u>

Result =  Sum \times 10

<u>Step 6: Divide by 2</u>

Result =  Sum \times 10 \div 2

Result =  Sum \times 5

This means that, the algorithm simply multiplies the sum of the rolls by 5

<u>Option (a): If step 6 is 10, 20, 30, 40, 50 or 60, then sum is even</u>

Make Sum the subject in Result =  Sum \times 5

Sum = \frac{Result}{5}

When 10, 20, 30, 40, 50 and 60 are divided by 5, the result is:

Sum = 2, 4,6,8,10, 12

All the above numbers are even number.

This means that, the sum is an even number.

<em>Hence, (a) is true</em>

<u>Option (b): If the last digit of step 6 is 5, then the sum is Odd.</u>

The possible sum of two rolls of dice, where the last digit ends in 5 are:

5, 15, 25, 35

When each of these are divided by 5, the result is:

Sum = 1,3,5,7

It is not possible to have a sum of 1 for two rolls

So, we have:

Sum = 3,5,7

All the above numbers are odd.

This means that, the sum is an odd number.

<em>Hence, (b) is true</em>

So, we can conclude that the true conditions are:

(a) and (b)
