the energy transfer diagram represents the energy of a person diving into a pool. how much thermal energy is generated? 1000 j 2000 j 7000 j 15,000 j gravitational potential energy 8,000 j kinetic energy 7,000 j thermal energy? j
Answer
Explanation:
Step1: Apply energy - conservation principle
The initial gravitational potential energy is converted into kinetic energy and thermal energy. According to the law of conservation of energy, the initial gravitational potential energy $E_{p}$ is equal to the sum of the final kinetic energy $E_{k}$ and thermal energy $E_{th}$. So, $E_{p}=E_{k} + E_{th}$.
Step2: Rearrange the formula to find thermal energy
We can rewrite the formula as $E_{th}=E_{p}-E_{k}$. Given $E_{p} = 8000\ J$ and $E_{k}=7000\ J$. Then $E_{th}=8000 - 7000$.
Step3: Calculate the thermal energy
$E_{th}=1000\ J$.
Answer:
1000 J
