Paul swings a 1.5 kg weight in a circle on the end of a 2.5 meter string at a velocity of 2.0 m/s. Calculate the centripetal force applied to the weight by the string.

Fc=mv^2/r

Explanation:

m=1.5 kg

r=2.5 m

v=2.0m/s

Fc=mv^2/r

Fc=1.5*2^2/2.5

Fc=1.5*4/2.5

Fc=1.5*4/2.5

Fc=6/2.5

Fc=2.4 N

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
