= 5.0 s/m
; &
The electric field intensity of the material E = 250 sin(10¹⁰ t) V/m
(a) The conduction current density 


(b) Displacement current density 
Recall that:

∴



(c) The frequency at which
will have the same magnitude is:

By substitution


f = 90 GHz
Answer:
28 grams
Explanation:
The equation for the reaction is
3H(2) + N(2) -> 2NH(3)
Then we have.
The molar mass, M of ammonia is 17 g/mol.
34 grams of ammonia, NH3 then would be
34 g / 17 g/mol
= 2 moles
2 moles of ammonia will be obtained from
(2 * 1) / 2
= 1 mole of nitrogen
The molar masses of nitrogen is 28 g/mol
2 moles of nitrogen corresponds to 1 * 28 = 28 grams.
I do not know if it is correct but I think it is between B or C
Answer:
Option (C)
Explanation:
Einsteinium is an element of the periodic table grouped in the Actinide series, with atomic number 99. They are dense element and highly electro-positive. <u>They are highly radioactive</u>, i.e the atoms within the element are unstable and constantly decay until they reach a stable environment. It has 99 number of electrons and protons, 153 number of neutrons.
Due to its high radioactivity, they are health hazardous and can used in making nuclear weapons but their uses are very limited and unknown.
Thus, the correct answer is option (C).
