Answer:
Explanation:
Initially no of atoms of A = N₀(A)
Initially no of atoms of B = N₀(B)
5 X N₀(A) = N₀(B)
N = N₀
N is no of atoms after time t , λ is decay constant and t is time .
For A
N(A) = N(A)₀
For B
N(B) = N(B)₀
N(A) = N(B) , for t = 2 h
N(A)₀ = N(B)₀
N(A)₀ = 5 x N₀(A)
= 5
= 5
half life = .693 / λ
For A
.77 = .693 / λ₁
λ₁ = .9 h⁻¹
= 5
Putting t = 2 h , λ₁ = .9 h⁻¹
= 5
= 30.25
2 x λ₂ = 3.41
λ₂ = 1.7047
Half life of B = .693 / 1.7047
= .4065 hours .
= .41 hours .
<h2>Answer:</h2>
Shown in the explanation
<h2>Explanation:</h2>Position vector of a particle at a given instant is given by:
On the other hand, the average velocity is the change in the particle’s position vector divided by time interval:
So we have:
Finally, the average velocity is:
