The electric potential, when measured at a point equidistant from two particles that have charges equal in magnitude but of oppo
1 answer:
Answer:
V = 0
Explanation:
To find the potential at the middle of the two charges with opposite signs, you use the following formula:
(1)
where you have used the fact that the charges are the same and the distances are the same.
The electric potential is zero at the point in the middle of the two charges

Explanation:
Bosons Particles are particles that condense to the same state. Bosons particle have integral spin like 0 , ,
,
, etc. Bosons particles always have asymmetric wave function and there is exchange of particles.
1) It does not obey Fermi_ Dirac statistics
2) It obeys Bose-Einstein statistics
3) The object can have intrinsic spin
4) Yes the Bosons particle is always symmetric with exchange of particles
5) No Bosons particle are symmetric and not asymmetric
(a) 0.249 (24.9 %)
The maximum efficiency of a heat engine is given by
where
Tc is the low-temperature reservoir
Th is the high-temperature reservoir
For the engine in this problem,
Therefore the maximum efficiency is
(b-c) 0.221 (22.1 %)
The second steam engine operates using the exhaust of the first. So we have:
is the high-temperature reservoir
is the low-temperature reservoir
If we apply again the formula of the efficiency
The maximum efficiency of the second engine is
