What is the maximum mass that can hang without sinking from a 60-cm diameter styrofoam sphere in water? assume the volume of the mass is negligible compared to that of the sphere.

the maximum mass suspended to the styrofoam sphere is m = 113.1 kg

Explanation:

The weight due to suspended mass is counterbalanced by the buoyancy force on the sphere

So here we will say

as we know that the maximum buoyancy force that will act on the styrofoam sphere is given as

now from above equation we have

so the maximum mass suspended to the styrofoam sphere is m = 113.1 kg

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
