Which direction does the decimal move from mega meters to meters
Temka [501]

To solve this problem, let us first understand what does mega meters mean. Now by definition, mega means a factor of one million which is a unit prefix in Metric Systems of units. It is denoted by the unit symbol M.

So for example if we have a mega of something, it means a million of something. So in this case, if we have 1 mega meter, what it means is 1 million meter, which is written as:

1 mega meter = 1,000,000 meter

 

To show the decimal points:

1.0 mega meter = 1,000,000.0 meter

 

So we see that the decimal point move 6 zeroes to the right, therefore the direction is to the right.

 

Answer:

<span>6 places to the right</span>

The student is now told that the four solids, in no particular order, are barium chloride (BaCl2BaCl2), sugar (C6H12O6C6H12O6),
iogann1982 [59]

Answer:

Explanation:

The concept applied is the conductivity as it relates to the dissociation and the number of ions in solution. BaCl2 and KBr are ionic solids that will dissociate completely in water to give trivalent and divalent ions respectively.

Benzoic acid on the other hand is a weak acid as such it will not dissociate in water. sugar is a covalent compound.

Hence BaCl2 will have the highest conductivity based on the aforementioned reasons, then followed by KBr ; BaCl2 > KBr > C6H5COOH > C6H12O6
