Janice has just measured the density of an object. Which value is possible? (Density: D = )
WHICH ONE!!!
To determine which value is possible for the density of an object, we need to understand the formula for density.
Density (d) is equal to the mass (m) of the object divided by its volume (v):
d = m / v
Density is typically expressed in units of mass per unit volume, such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
Let's consider the options provided:
A. -1 g/cm³
This option is possible, as density can be negative. However, negative density values are generally not encountered in physical objects and are mostly theoretical or mathematical constructs.
B. 4 m/s
This option is not possible because the unit of measurement for density is grams per cubic centimeter (g/cm³) or a similar unit, not meters per second (m/s). Therefore, this value does not correspond to an appropriate measurement for density.
C. -3 m/s
Similar to option B, this value is not possible for the same reason. Density is not measured in meters per second (m/s).
D. 6 g/cm³
This option is possible and corresponds to a valid density measurement in grams per cubic centimeter (g/cm³).
In summary, the possible value for the density of an object among the given options is D. 6 g/cm³.
mass / volume
there are two answers with the correct units
... one of them is negative ... not realistic
