Answer:
47.91 sec
Explanation:
it is given that
at t=0 velocity =0 ( as it is given that it is starting from rest )
we have to find time at which velocity will be 3.3
we know that
integrating both side
---------------eqn 1
at t=o it is given that v=0 putting these value in eqn 1 c=0
so
when v= 3.3
t=
=47.91 sec
Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence,
