The gold foil experiment performed in rutherford's lab gold foil experiment performed in rutherford's lab

Ernest Rutherford is well known for his nuclear theory of the atom with his gold-foil experiment. When he shot a ray of alpha particles at a sheet of gold foil, a small number of the particles were bounced. He concluded that a small, dense nucleus was producing the deflections. This experiment concluded that every atom contains a nucleus where its positive charge and most of its mass are concentrated. Thus, led to the discovery of the atomic nucleus.

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
