Answer:
elastic partial width is 2.49 eV
Explanation:
given data
ER E = 250 eV
spin J = 0
cross-section magnitude σ = 1300 barns
peak P = 20ev
to find out
elastic partial width W
solution
we know here that
σ = λ²× W / ( E × π × P ) ...................1
put here all value
σ = (0.286)² × W × 
/ ( 250 × π × 20 )
1300 × 
= (0.286)² × W × / ( 250 × π × 20 )
solve it and we get W
W = 249.56 × 
so elastic partial width is 2.49 eV
Answer:
The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.
Explanation:
- ELECTROLYTES are salts or molecules which ionize in solution fully.
- Electrolyte solutions thus conduct electricity readily.
whereas
- NON ELECTROLYTES in water do not dissociate from ions,
- non-electrolyte solutions do not conduct electricity.
1. Air resistance force usually upwards, but gravity doenwards.
2. Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent.
Sorry if im wrong
B. An apple about to fall from a tree branch
This is because potential energy is the energy before its actuall motion, or before kinetic energy (energy in motion). And the apple ABOUT TO FALL mentions a gravitational example.
The pressure of a liquid on the surface of its container or on the surface of any body in the liquid is equal to the weight of a column of the liquid whose height equals the depth of the liquid at that certain point.
