We know that impulse is simply the product of Force and time:
Impulse = Force * time
Since Force has a unit of Newton or kg m/s^2 and time is in
seconds, therefore impulse can have units as:
N s
or
<span>kg m/s</span>
An Energy Transfer Diagram is also known as Sankey diagram and this shows the input energy taken in and the transformation of the output energy in another form. Therefore the basis for analyzing an energy transfer diagram would be the sum of all outputs must equal the input. Therefore, it is the third option. Hope this answer helps.
Astrophysics is the answer
<u>Given data:</u>
M.A. = 8 (No units),
Ramp height (h)= 1.5 m, lifted,
Determine how long is the ramp=?
<em>General formula </em>
<em> Mechanical Advantage = (Ramp length) ÷ (Ramp height),</em>
<em> M.A = l ÷ h </em>
<em> 8 × 1.5 = l = 12 m long</em>
<em>length of the ramp l ramp = 12 m</em>
