Work is calculated by multiplying the amount of force exerted and the distance that the object had moved. From the given above, the work that the forklift does is calculated by,
W = F x d
W = (2.00 x 10^3 N)(5 m)
V = 10 x 10^3 N.m
Thus, the work done is approximately 10,000 J.
Explanation:
Pure substances are typically elements and compound with the following characteristics:
- Pure substances are distinct substances.
- They are homogeneous in all their parts i.e they are the same all through.
- They have a definite composition
- They cannot easily be separated or broken down into simpler substances by physical means.
- Separation by physical means is not easy
- They have a unique sets of physical properties
Impure substances are mixtures. They have the following features:
- Their composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass.
- Constituents retain their identities i.e physical properties are retained.
- The constituents reacts differently to changed conditions.
- They can easily be separated into their constituents by physical methods.
