Density is a property of an object or substance that can be described through the correlation of the mass of an object over its volume.
Mathematically, density = mass / volume.
In description, the relationship of density and mass is positively correlated and with volume, inversely.
Since density and mass is positively correlated then if you increase the mass, the density of the object will also increase leaving density and volume the same.
Example:
Mass = 10 g changes to 20
Volume = 5 cm3
Density =?
1. D = m / v
2. D = 10 g / 5 cm3
3. D = 2 g / cm3
4. D = 20 g / 5 cm3
5. D = 4g/cm3
Answer: 240.25joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
Thus, Workdone = Force x distance
Since, Work = ? (unknown value)
Force = 77.5N
Distance = 3.1metres
Workdone = 77.5 N x 3.1metres
= 240.25 joules
Thus, Amanda did a work of 240.25joules on the crate
