Convection is the answer i
think
Answer:
Kinetic Energy at bottom=2886.5J (when g=9.8m/s²)
<em><u>OR</u></em>
2925J (if g=10m/s²)
<h3>Answer:</h3>
the dishes and silverware are in inertia of rest
<h3>Explanation:</h3>
Newton's first law of motion is that things at rest tend to stay at rest unless acted upon by an external force.
A silk tablecloth will have a fairly slippery surface, so there is not much friction to cause tableware to be accelerated.
Answer:
<h2>To solve typical questions like this we can use law of conversation of linear momentum...which is</h2>
<h2>T.I.L.M.=T.F.L.M.</h2>
(Total initial linear momentum = total final linear momentum.)
<u>Momentum = mass × velocity</u>
<h2>T.I.L.M = T.F.L.M</h2>
180×4 + 120×0 = 180×0 + 120×V
(180 ×4)/120 = V
<h2>6Ms^-1 = v</h2>
