Answer:
Explanation:
Given
Mass of object (m)=6 kg
falling height(h)=10 m
mass of water(
)=600 gm
temperature of water =15
specific heat of water 
Let T be the Final Temperature of water
Here Object Potential Energy is converted into Heat energy which will be absorbed by water
Potential Energy(P.E.)
Heat supplied
T-16=0.234
This is not an efficient way of heating water as there is only
increase in temperature.
Answer:
Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years.
Explanation:
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.

Explanation:
Answer:
<em>Aim at the base of the fire and use short bursts until the fire is out.</em>
<em></em>
Explanation:
Fire extinguishers use CO2 (Carbondioxide) as the extinguishing agent. This is because CO2 is denser than air, and does not support combustion.
Aiming at the base of the fire causes the CO2 to fall on the base of the fire, where the source of the fire is, trapping it, and preventing it from further reacting with air in a combustion reaction. Also, the short burst creates a strong wind that forces the flame to blow out.
