In chemistry, a valence electron is an outer shell electron that is associated with an atom and that can participate in the formation of a chemical bond only the outer shell is not closed. So, the answer to this question wold be outermost energy level.
Answer:
<h2><u>Given </u><u>:</u><u>-</u></h2>
- Mass = 3 kg
- Velocity = 10 m/s
<h2><u>To</u><u> Find</u><u> </u><u>:</u><u>-</u></h2>
Kinetic energy
<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
We know that
KE = ½ × Mass × Velocity
KE = ½ × 3 × 10
KE = 3 × 5
KE = 15 J
In the given equation :
If three physical quantities is to be added or subtracted, they must have same dimensions.
So, dimension of y = dimension of c(t²)
And we already know,
- y = M⁰L¹T⁰ [ since it represents distance/length ]
- t = M⁰L⁰T¹ [ since it represents time ]
( by squaring )
Now, we need to calculate dimension and unit of c :
Now, we got the dimension of c as :
So, it's SI unit will be :
[ since SI unit of length/distance = m, and SI unit of Time = sec, hence SI unit of T² = s² ]
