Explanation by: Tony S [ Return to question menu
]Answer 1
.0005 kg INCORRECT A nickel is very small, and using kilogram to gram conversion we see that this only has a mass of .5 grams. A paper clip is a good unit of measure it has a mass of approximatly 1 gram. This is only half a gram! return to top
Answer 2
.005 kg CORRECT!!! This is correct because if you use kilogram to gram conversion .005 kg is equal to 5 grams. This is roughly the mass of a nickel. (About 5 paper clips). return to top
Answer 3
.5 kg INCORRECT This is not correct because .5 kg is equal to 500 grams, which is much to heavy for a nickel. That would be roughly 500 paper-clips. return to top
Answer 4
5 kg INCORRECT Just as the previous answer, this mass is much to large. Using the kilogram to gram conversion we see that it would be 5000 grams. Which is FAR to large a number. return to top
What's this question really asking?
This question is asking two things: first whether or not you understnad the concept of unit conversions (in this case KG to G), secondly using common sense on how much a nickel may actually weight! return to top |
