<span>KE = 1/2mv^2
KE = 1/2(8)4 m/s^2
KE = 4*4
KE = 16 Joules
Kinetic energy would equal 16 J </span>
Answer:
becomes runoff and finds its way back to the ocean
Explanation:
Precipitation refers to rainfall that reaches the earth.
Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.
When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.
Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean
In the lake that the rivers lead, water molecules evaporate into the sky and form clouds. In the sky, these water droplets condense and form clouds that will eventually rain.
Answer:- C. H
Explanations:- Reduction is gain of electron. In other words we could say that decrease in oxidation number is reduction.
As per the rules, oxidation number of hydrogen in its compounds is +1(except metal hydrides) and the oxidation number of oxygen in its compounds is -2.
The oxidation number in elemental form is zero.
In 
, the oxidation number of H is +1 and oxidation number of O is -2. Oxidation number of Cl in 
is -1. On product side, the oxidation number of hydrogen in 
is zero and in 
the oxidation number of H is +1 and that of O is -2. Oxidation number of Cl in 
is 0.
From above data, Oxidation number of O is -2 on both sides so it is not reduced.
Oxidation number of Cl is changing from -1 to 0 which is oxidation.
Oxidation number of H is changing from +1 to 0 which is reduction.
So, the right choice is C.H
