2NO2 means that there is 2 oxygen atoms and one nitrogen with two sets of that. So its the third one
Answer:
E= -3.166 cosωt V
Explanation:
Given that
I = Imax sinωt
L= 8.4 m H
Imax= 4 A
f = ω/2π = 60.0 Hz
ω = 120π rad/s
We know that self induce E given as




E= -3166.72 cosωt m V
E= -3.166 cosωt V
This is the induce emf.
Density= how much mass is in a certain volume
Therefore, you do (mass/volume).
density of the block is
36g/9cm3
or
4g/cm3
Meaning that there is 4 grams of mass in each cm3.
