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:d
Explanation:1 times 1.63 times 2
1. A) In chemical equilibrium
The sign between the reactants and products is used to represent a chemical equilibrium. In a chemical equilibrium, the rate at which product is being produced is the same as the rate at which the product is being consumed to form the reactant again.
2 B) More products form
This is in accordance to Le Chatelier's principle, which basically states that a reaction mixture at equilibrium will resist any change that is produced in it. Therefore, if the temperature is increased, the mixture will move towards the products side, which has a lower temperature due to it being an endothermic reaction.
3 A) Saturated
<span>When a solution is saturated, it is no longer able to dissolve any more solute within it. A crystal of solute sitting at the bottom is an indicator that no more solute can be dissolved, meaning the solution is saturated.</span>
<span>Wind power is produced from the
wind turbines or sails that uses air flow to convert it into mechanical power. It
is an alternative to fossil fuel burning, it is all around, renewable, clean,
produces no greenhouse gases and uses little land. The advantages of wind power
have been greatly praised by many. However, it has disadvantages. Wind power
especially at farm is noisy and may spoil the view for their neighboring people.
Also the amount of electricity depends on the strength of the wind. If no wind
is around, no electricity is produced. </span>
