A compound inequality<span> is an equation with two or more </span>inequalities<span> joined together with either</span>
I think the answer is A but I’m not 100% sure
Answer:
He won 32 games.
Explanation:
<em>Another way of expressing 75% is 75/100.</em>
To calculate how many games the baseball pitcher won, we <u>multiply the total of games played</u> (43, in this case) by the percent won:
43 * 75/100 = 32.25 ≅ 32
So the baseball pitcher won 32 games.
Answer:
First option:
[NH3]2 / [N2][H2]3
Explanation:
First of all we need to determine the reaction:
N₂(g) + 3H₂(g) → 2NH₃(g)
1 mol of nitrogen can combine with 3 moles of hydrogen to produce 2 moles of ammonia.
Remember that Kc has to involve Molar concentrations of products / reactants
Concentration must be elevated to the stoichiometry coefficient
Kc for the reaction is: [NH₃]² / [N₂] . [H₂]³
Answer:
1 that is 100%
Explanation:
here it is given that Fermi energy of the of the metal = 5 e.V
work function= 4 e.V
we have to find the probability that an incident electron will tunnel out if E=109 V/m
WORK FUNCTION : work function is defined as the energy required to withdraw an electron completely from the metal surface.
now the energy per unit volume in electric field is given by
E= 
E=
E=
in electron volt E=4.427\times 10^{6}joule × 6.24\times 10^{18}
E=
hence the applied energy per unit volume is greater than the work work function of electron so there is probability of 100% that electron will tunnel out
