Answer:
<em><u>0</u></em><em><u>.</u></em><em><u>9</u></em><em><u>1</u></em>
Explanation:
as equivalence resistance can be found out using the
1/Req = 1/r1 +1/r2 +1/r3......
now, 1/req= 1/2+1/3+1/4
=6/12+4/12+3/12
=13/12
i.e, req =12/13 =0.91

The force of attraction between the opposite charges of the ions in an ionic compound is an ionic bond.
<u>Explanation:</u>
The transfer process of valence electron between atoms referred as ionic bond. This is a kind of chemical bonds which can create two oppositely charged ions. In the presence of ionic bonds, the metal loses electrons and becomes a positive charge cation, while non-metal accepts these electrons and becomes a negative charge anion.
Here, more than 1 electron can be emitted or received to meet the octet principle and the net charge of the compound should be zero. For example: Table salt. In this compound, sodium loses the electron to become , while the chlorine loses the electron to become .
Answer:
so separation between slit is 0.12 mm
Explanation:
given data
slit wide = 0.020 mm
wavelength λ = 589.6 nm
fringe pattern n = 11
to find out
separation between the slits
solution
we know that for maxima we can say
d sinθ = m × λ .........1
and m is mth order maxima
and for central maxima
number of bright fringe is here
N = 2m -1
11 = 2m - 1
m = 6
so here number of maxima on either side of central maxima will be m-1
that is = 5
because we know 6th maxima will be minimized by minima
so
condition for minima is
a sin(θ) = n × λ
now for 1st minima
a sin(θ) = λ
and
= m
d = ma
d = 6 × 0.02
d = 0.12 mm
so separation between slit is 0.12 mm
The answer is to maintain safety.
