What is the mass of an object if a force of 45 N causes it to accelerate at a rate of0.75 m/s2? *

60kg

Explanation:

Data obtained from the question include:

F (force) = 45N

a (acceleration) = 0.75 m/s2

m (mass) =?

Force is simply the product of mass and acceleration as given from the formula: F = ma. With this formula (i.e F = ma) we can easily calculate the mass of the object. This is illustrated below:

F = ma

m = F/a

m = 45/0.75

m = 60kg.

Therefore, the mass of the object is 60kg

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
