Answer:
1. 1.96 g/L
2. 1 g/cm³
Step-by-step explanation:
Density is found by dividing mass by volume: d = m/v.
1.
We know that the mass is 0.196 grams, while the volume is 100 mL.
Converting the volume to liters, we get:
100 mL = 0.1 L
Then, applying our density formula:
d = m/v
d = 0.196 g / 0.1 L = 1.96 g/L
2.
Here, we know that the mass is 27 grams. However, we don't know the volume, which we need to find.
The block of wood is 3 cm on all sides, which means it's a cube. The volume of a cube is denoted by V = s³, where s is the side length. Here, s = 3, so V = s³ = 3³ = 27 cm³.
Applying our density formula gives:
d = m/v
d = 27 g / 27 cm³ = 1 g/cm³

keeping in mind that a year has 12 months, thus 6 months is really 6/12 of a year.
18 groups of 12. 18 times 12. That equals 216. 216 can round to 200, 215, or 220.
Converting to spherical coordinates, we have
On the other hand, we can parameterize the boundary of
by
with
and
. Now, consider the surface element
So we have the surface integral - which the divergence theorem says the above triple integral is equal to -
as required.
