Answer:
The radius of the sphere is 3.6 m.
Explanation:
Given that,
Potential of first sphere = 450 V
Radial distance = 7.2 m
If the potential of sphere =150 V
We need to calculate the radius
Using formula for potential
For 450 V
....(I)
For 150 V
....(II)
Divided equation (I) by equation (II)
Hence, The radius of the sphere is 3.6 m.
Answer:
time is 3333.33 min or 55.55 hr
Explanation:
given data
reactor operating = 1 MW
negative reactivity = $5
power = 1 miliwatt
to find out
how long does it take
solution
we know here power coefficient that is
power coefficient =
power coefficient = 1
so time required to reach power is
power = reactivity × time / power coefficient + reactor operating
1 × = -5 t / 1 + 1 ×
5t = -
t = 199999.99 sec
so time is 3333.33 min or 55.55 hr
