lester prepares to lift a heavy sack of flour into a customer’s shopping cart. during which part of the action does lester do work?

when he applies force to the sack before lifting it

when he holds the sack against his chest

as he lets go of the sack and it falls onto a cart

as he lifts the sack to his chest from the floor

Option (d) is the correct answer.

Explanation:

Work is defined as the force applied in order to move an object from a certain distance.

Mathematically,         W = F × d

where,       w = work

                  F = force

                  d = distance

Thus, when Lester lifts the sack to his chest from the floor then he is doing work as he is applying force on the sack in order to move it over his chest.

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

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
