If the machine's mechanical advantage is 4.5, that means that
Output force = (4.5) x (Input force) .
We know the input force, and we need to find the output force. Rather than wander around the room looking at the floor while our hair smolders, let's try putting the numbers we know into the equation I wrote up there. OK ?
Output force = (4.5) x (Input force)
Output force = (4.5) x (800 N)
Now dooda multiplication:
<em>Output force = 3,600 N</em> .
That's exactly what the question asked for. So we're done !
I think being self disciplined is when you are a responsible and mature person and maybe raised yourself I don’t know what else to write you can expand on this
Answer:
density of water is much greater than density of air
Explanation:
when body is in fluid it carries weight which is always equal to upthrust
upthrust is given as
upthrust= density of fluid ×strength of gravitational field g × volume of body in fluid
as volume of ship and aeroplane is same and strength of gravitational field or acceleration due to gravity is same hence upthrust depens upon density of fluid .
density of air is about 1.2 kg/m^3 and density of water is 1000kg/m^3 hence ship carries more load
I don't know if you need to complete this question or do it otherwise, however, I managed to find on the Internet on several places this completion of your sentence:
<span>Electric current flows through a long rod generating thermal energy at a uniform volumetric rate of q = 2 x 10</span>⁶ W/m³.
I'm not sure whether that is the answer you were looking for, but that's what I found.
