A bucket of unstretched springs (k=8 N/m) resting on the ground. Calculate the bucket's Mechanical Energy in [J}

0 J

Explanation:

The mechanical energy of a spring is given by where k is spring constant and x is extension of spring. Since the spring is unstretched,  its extension is zero.

#Notice that the potential energy is 0.

-Substituting spring constant,  k with 8 and extension with zero then the mechanical energy will be

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

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
