Heat engines are less than 100% efficient because absolute zero cannot be reached
Answer:
3
Explanation:
v = v⁰ (its original speed) + a (negative acceleration) X t² (time)
v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)
It's is True that your body temperature your body converts chemical potential energy into thermal energy
Change in position of object = Displacment
Here’s my work to your question. I used Newton’s Second Law and a kinematics equation to arrive at the answer.
