Explanation:
To solve this problem we will apply the theoretical concepts and definitions given for the specific weight, density and specific gravity. Consider also that a barrel contains 159 liters or
Consider the net weight of the oil which would be
The specific weight is defined as the proportion of weight by volume thereof, therefore
Through the information given we could find mass and density through the following relations:
Mass
Density
Specific gravity,
Answer: It was on between 7 and 7.30 and also between 8 and 8.30 (when the line on the graph goes up only). So it was on for an hour or 60 minutes
Your hypothesis can be that the group with calculators would finish faster than the group without calculators.
