Answer:

0.003125 msv

Explanation:

I_1 = Initial Exposure = 0.05 msv

I_2 = Final Exposure

D_1 = Initial distance = 1.5 ft

D_2 = Final distance = 6 ft

Exposure is inversely related to the distance squared (inverse square law)

I\propto \dfrac{1}{D}

So,

\dfrac{I_1}{I_2}=\dfrac{D_2^2}{D_1^2}\\\Rightarrow I_2=\dfrac{I_1D_1^2}{D_2^2}\\\Rightarrow I_2=\dfrac{0.05\times 1.5^2}{6^2}\\\Rightarrow I_2=0.003125\ msv

The exposure at the given distance is 0.003125 msv

Setler79 [48]
The correct answer is easy child.
No child is undemanding - parents have to be around their baby at all times, caring for it, and tending to its every need. But this child can easily adapt to anything, which is why she doesn't really take up a lot of her parents' time, and doesn't cause problems.
