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
Answer:
<h3>The answer is 0.54 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula

From the question we have

We have the final answer as
<h3>0.54 g/cm³</h3>

Answer:
work done will be equal to 305.05 J
Explanation:
We have given force exerted F = 45 N
Angle with the horizontal 
Distance moved due to exerted force d = 9.1 m
Work done is equal to
, here F is force
is angle with horizontal and d is distance moved due to force
So work done 
So work done will be equal to 305.05 J
