Ablock with a mass of 9.00 kg is pulled at a constant speed across a horizontal tabletop with a spring scale. the scale reads 61.8 n. calculate the coefficient of kinetic friction

0.69

Explanation:

Coefficient of kinetic friction=f/R=61.8/90=0.69

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

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
