What buoyant force does a 0.60-kg solid gold crown experience when it is immersed in water? the density of gold is 19.3 × 103 kg/m3 and that of water is 1000 kg/m3.

W = 0.3045 N

Explanation:

given,

mass of the object = 0.6

density of gold = 19.3 x 10³ kg/m³

density of water = 1000 Kg/m³

buoyant force = ?

Volume of the crown=

density = mass/volume

V = 3.108 x 10⁻⁵ m³

W = ρ V g

W = 1000 x 3.108 x 10⁻⁵ x 9.8

W = 0.3045 N

Buoyant force acting on the crown is equal to W = 0.3045 N

which statement about this sum is true? −245+2.7

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
