Question 6 (5 points)
(03.05 mc)
a hot air balloon holds 1,592 cubic meters of helium. the density of helium is 0.1785
kilograms per cubic meter. how many kilograms of helium does the balloon contain,
rounded to the nearest tenth of a kilogram? (5 points)
1) 432.3 kg
o2) 284.2 kg
o3) 2,043.7 kg
4) 5,435.3 kg

2) 284.2 kg

Step-by-step explanation:

Density, mass and volume

We know the density of certain mass m who occupies a volume v is:

Our hot air balloon holds a volume of 1,592 m^3 of helium. Knowing the density of helium is 0.1785 kg/m^3, we can solve for the mass

Rounding to the nearest tenth:

The correct option is 2)

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
