Answer:
spacing is 0.8307 mm
Explanation:
given data
wavelength = 500 nm
interference fringes N = 1.5 mm
wavelength = 640 nm
to find out
spacing between the fringes
solution
we know bright fringe spacing in double slit is express as
w × sinθ = N × wavelength
so angle is
sinθ = N × wavelength / w
and spacing is express as
spacing = d sinθ
and that is = N × (d/w) × wavelength
so
spacing = 1.5 × 360 / 650
so spacing is 0.8307 mm
Answer:
a) x = 0.200 m
b)E = 3.84*10^{-4} N/C
Explanation:
DISTANCE BETWEEN BOTH POINT CHARGE = 0.5 m
by relation for electric field we have following relation
according to question E = 0
FROM FIGURE
x is the distance from left point charge where electric field is zero
solving for x we get
x = 0.200 m
b)electric field at half way mean x =0.25
E = 3.84*10^{-4} N/C
In <u>370 K to 375 K </u>temperature intervals of 5 K, would be the greatest increase in the entropy of the sample.
Option: C
<u>Explanation</u>:
Because the largest difference in molar entropy occurs when a condensed phase (solid/liquid) transforms to the gas phase. Then change in entropy is equal to heat transfer divided by temperature: .
According to given ice sample at 260 K, when this solid sample start converting into liquid sample it will gain positive temperature and steam will take place near 373 K (273 K ice temperature + temperature of boiling water). Therefore it’s very obvious that greatest increase in entropy will occur during 370 K – 375 K.
