Question

Identify each of the following as measurements? length,area,volume,mass,density,time,temperature a. 5 ns b.5.5kg/m^3 c.0.88 pm d.540km^2 e.173 K f.2 mm^3 g.23 C

Answer 1

Do you have any guesses?

Answer 2

I think the trickiest one to identify might be density, but just remember that it is mass/volume

Answer 3

An area measurement should be in units \(\large(\text{length})^2\), and volume in units \(\large(\text{length})^3\)

Answer 4

time, mass, density, temperature, volume, and temperature?

Answer 5

I think we should break down the units:
ns: nanoseconds
kg/m^3: kilograms/metre^3
pm: picometre
km^2: kilometre^2
K: Kelvin
mm^3: millimetre^3
C: I'm guessing this is for (degree) Celsius, but it should be technically °C . Otherwise C would stand for Coulomb, but that's for electric charge and doesn't correspond to any of your choices.

Answer 6

since Kelvin is a unit of temperature, does that mean density will not be used?

Answer 7

there is a density in your problem. remeber is is a mass/volume, or a mass/length^3

Answer 8

it is*

Answer 9

okay, so I'm guessing that mass is the unit that is not being used?

Answer 10

yeah

Answer 11

so are the answers time, density, length, area, temperature, volume, and temperature?

Answer 12

yeah I would go with that

Answer 13

Thank you so much!!
