The acceleration : 0.25 m/s²
<h3>Further explanation</h3>
Given
mass = m = 24 kg
Force = F = 6 N
Required
The acceleration
Solution
Newtons' second law :
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
ΣF = m x a
Input the value :
6 N = 24 kg x a
a = 6 : 24
a = 0.25 m/s²
I definitly believe the answer is c. 2
The molecular formula for sodium chloride is NaCl. The sum of their atomic weights is (22.99 grams/mole + 35.45 grams/mole) = 58.44 grams/mole
take (17.0 grams)/(58.44 grams/mole), which equals 0.291 moles of NaCl.
Answer: 1.324L
Explanation: use Boyles law, sorry so late!
What iron gives in its abundance, it takes away in it's inability to really conduct heat and electricity well. There is enough copper around, if we are careful in its use, to make copper bottomed pots and pans. Of the three best conductors in the world (silver, gold and copper) only copper has enough around and can be inexpensively mined that we make use of it.
If you google dr. copper, you will find he is an economist as well. Copper measures the wealth of an economy by how much is used. So iron might be cheaper and more abundant, but copper will save you much more in trying to do something with it.
