How much work is done by the force lifting a
0.1-kilogram hamburger vertically upward at
constant velocity 0.3 meter from a table?
(1) 0.03 j (3) 0.3 j
(2) 0.1 j (4) 0.4 j

The work done in lifting the hamburger is equal to the increase in gravitational potential energy of the hamburger, given by

where

m=0.1 kg is the mass of the hamburger

is the gravitational acceleration

is the increase in height of the hamburger

Substituting numbers into the equation, we find

So, the correct answer is

(3) 0.3 J

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
