Answer:
A., an action which causes movement and an opposite reaction
Explanation:
I don't really know how to explain it, but this helped hopefully! :) Have a bless day
Lenz's Law: The polarity of the induced emf is such that it produces a current whose magnetic field opposes the change in magnetic flux through the loop.
Answer:
Explanation:
The main difference is that states with spin angular momentum in the same direction of the field are more high energy that the states with antiparallel spin agular momentum.
The energy for a particular level is
E = -(γ*h/2*π)*m*B
where γ is a constant about magnetic moment, h is the Planck constant, m is the state level and B is the strength of the magnetic field. Its clear that for antiparallel spins m=-1/2 the energy is lower in comparisson with states with m=1/2
In fact
ΔE = γ*h*B/2*π
Answer:
change in entropy is 3.3034 × 
Explanation:
give data
thermal energy Q = 155 J
temperature T = 340 K
to find out
change in entropy
solution
we know change in entropy formula that is
change in entropy = Q / ( K×T ) ..............1
here K is boltzmann constant that is 1.38 × 
kg-m²/s²
put these value in equation 1 we get
change in entropy = Q / ( K × T )
change in entropy = 155 / ( 1.38 × × 340 )
change in entropy = 3.3034 ×
so change in entropy is 3.3034 ×
