Answer:

Sustainable energy is essential to meet uncontrolled rising demand for energy, reduce pollution and shift to resources that can be used again and again.

Explanation:

Considering the Sustainable Goals floated by United Nation, it is essential for all countries to improve their score in all the SD goals.

One of the SD goal is to shift to sustainable energy.

Sustainable energy is essential from following three points

- Reuse of energy source again and again to outcome the fear of resource depletion

- Sustainable energy source shall ensure cleaner environment

- Sustainable energy sources are also essential to meet the rising consumption of energy with time all across the globe.

Some common examples are - Solar energy, Wind Energy, Energy from nuclear fuels etc.

David lifts a book 1.2 meters from the floor to the top of his desk. If the book weighed 0.50 kg, what is the gravitational pote

Anika [276]

Answer:

5.886 J

Explanation:

Given:

The mass of the book is, $m=0.5$ kg

Height of lift is, $\Delta h=1.2$ m

Acceleration due to gravity is, $g=9.81$ m/s²

Now, gain in gravitational potential energy is a function of change in position and is given as:

$\Delta PE=mg\Delta h$

Here, $\Delta PE$ is the change in gravitational potential energy.

Plug in 0.5 kg for $m$ , 9.81 for $g$ and 1.2 for $\Delta h$ . Solve for $\Delta PE$

$\Delta PE=0.50\times 9.81\times 1.2=5.886\ J$

Therefore, the gain in gravitational energy of the book is 5.886 J.
