2. kinetic energy: due to it being transferred through collisions
The answer is D.
Hope this helps and have a good day :D
Energy is neither created nor destroyed
E in = E out
750 J in so 750 J out
Answer:
conduction
Explanation:
Conduction is a method of heat transfer, where two objects exchange heat by touching, but does not contribute to moving heat through earth's atmosphere, because the atmosphere is so sparse it does not transmit heat through conduction effectively. Insulation is not a method of heat transfer.
Answer:
(E) none of these.
Explanation:
first that all we need the meaning of a Watt
<em>" is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 </em><em>joule</em><em> per </em><em>second</em><em>,[1] and is used to quantify the rate of </em><em>energy</em><em> transfer." </em>
<em>definition taken from wikipedia.org</em>
now with this concept we have that:
100 W means 100 J/s .Therefore it uses 100 J energy per second
therefore on the answers don't mention this three terms together
Joules, energy and second so the answer must be.
(E) None of these
