Answer:
<h3>F=4k.gm/s^2</h3>
Explanation:
<h3>F=m×a</h3><h3>f=2k.g×2m/s^2</h3><h3>f=4k.gm/s^2</h3>
The advantages of the hydropower are:
- It is renewable
- It is a clean source of energy
- Matches current demand
- It is stable and reliable
- Requires low operating cost
The disadvantages of the hydropower are:
- Causes environmental damage
- Cost of building is expensive
- May cause droughts
- May cause floods in lower areas
- Shortage of water supply
The hydroelectric power has its prons and cons. It is very expansive for building, and it causes environmental damage in the river systems, but it also causes hazards like droughts and floods at certain areas. On the other side, once established it is very cheap, and it gets the job done when it comes to electricity. It is also an energy that is not polluting, and it is sustainable, reliable, and renewable.

Answer:
Explanation:
The states that all of the particles that make up matter are constantly in motion. As a result, all particles in matter have kinetic energy. The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas. ... Particles do not always move at the same speed.
The answers include:
- A loaf of risen but unbaked bread - chemical change.
- Photo by Elinor D - chemical change.
- Bread dough rising - chemical change.
<h3>What is a Chemical change?</h3>
This involves the formation of a new products from substances. In this scenario, a rising bread contains alcohol which evaporates.
Photographs also fall under this category and is therefore an irreversible chemical change.
