Answer:
Options (A), (B), (D), and (E).
Explanation:
Density is a physical property that describes the relationship between mass and volume. This property shows whether an object will float or it will get sink. The density of substances changes with the changing temperature, as both are inversely proportional to each other.
Mathematically, density can be written as,
Density =
ρ = , Where, ρ = density, m = mass, v = volume
Thus, the correct answers are options (A), (B), (D), and (E).
Answer:
Explanation:
The question says that, "The closest star to the earth is 2 light years away. Calculate this distance in SI units".
Given that,
The distance between the closest star and the Earth is 2 light years.
The SI unit of distance is m. It means we need to convert light years to meters. We know that,
2 light-years means,
So, the required distance is equal to .
