Answer:
T = 0.607 seconds
Explanation:
Given:
Mass, M = 1.50 × 10⁻² kg
Radius, R = 5.50 × 10⁻² m
Now,
the time period in terms of moment of inertia is given as:
.....................1
where, T is the time period
g is the acceleration due to gravity
I is the moment of inertia
Now,
Moment of inertia, I is given as:
on substituting the moment of inertia in the equation 1, we get
or
on substituting the valeus, we get
or
T = 0.607 seconds
Hence, the time period is 0.607 seconds
Answer:
at distance 18.33 ft no biological effects
Explanation:
given data
distance = 41 ft
radiation = 5 rem
to find out
how close get so no biological effects
solution
we know here that intensity of radiation R is inversely proportional to (radiation)²
so here equation will be
.............1
here I is intensity
so here I1 = 25
because for 0 to 25 there is no detectable effects and for 25 to 100 it will . temporary decrease so
we take 25 because dose is less than 25 so we take that highest value
so
R1 = 18.33 ft
so at distance 18.33 ft no biological effects
