Answer:
Explanation:
Given that
We know that
Rex=ρvx/μ
So
All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C
We also know that
Nux=hx/K
m is the constant
This is local heat transfer coefficient
The average value of h given as
---------1
The value of local heat transfer coefficient at x=L
-----------2
From 1 and 2 we can say that

1 micro gram of Strontium-90 has an activity of
0.0000053 terabecquerels (TBq),
Explanation:
Given information denotes that .,one gram of Strontium-90 has an activity of 5.3 terabecquerels (TBq)
the activity of 1 micro gram is
1 gram = 1,000,000 micro gram has activities of 5.3 terabecquerels
therefore 1 micro gram has the activity of (5.3 ÷ 1,000,000 = 0.0000053 )
=
Hence ., 1 micro gram of Strontium-90 has an activity of
0.0000053 terabecquerels (TBq),
