Answer:
3240000 ft
Explanation:
There are 60 seconds in a minute so, multiply 60 seconds by 18 minutes. That equals 1080 seconds.
Since there are 3000 ft in each second, just multiply 1080 seconds by 3000 ft.

Answer:
moving the boxes and the furniture up to the fifth floor.
Explanation:
The work done when moving an object up or down is equal to its change of gravitational potential energy:
where
m is the mass of the object
g is the gravitational acceleration
is the change in height of the object
We have two opposite situations:
1) when an object is moved upward, is positive, so the work done W is positive as well: this means that we need to do work in order to move the object, because we have to "win" the effect of gravity, which pulls the object downward
2) when an object is moved downward, is negative, so the work done W is negative as well: this means that we do not need to do work on the object, because it is already done by gravity, which pulls the object downward.
Therefore, more work is done when we are moving the boxes and the furniture up to the fifth floor.
I think its true, I think.
That is true. its more than twice as heavier
