Answer:
with the mirror into the right direction
Explanation:
Dalton's <span>law of partial pressures
</span>
Answer:
42.3 MV
Explanation:
d = diameter of the metal sphere = 2.15 m
r = radius of the metal sphere
diameter of the metal sphere is given as
d = 2r
2.15 = 2 r
r = 1.075 m
Q = charge on sphere = 5.05 mC = 5.05 x 10⁻³ C
Potential near the surface is given as
V = 4.23 x 10⁷ volts
V = 42.3 MV
Nuclear decay is spontaneous.
Nuclear fission does occur spontaneously but at a
very low level in fissionable materials. The main difference between fission
and nuclear decay is that fission can occur by neutron bombardment. And when
the neutron source is also other fissioning atoms, a chain reaction can may
happen. <span>
No chain reaction is possible with nuclear decay.
<span>That would be a much better characteristic to look at.</span></span>
