Answer:
volume of water is 0.1092 m3
Explanation:
We know that heat energy required to convert water into ice is given as
Q =mL
where L is Latent heat of fusion of ice is 336000 Jkg-1
=1000*V
Q = 1000V*336*10^3
Q = 336*10^6 V
ENERGY used by the freezer is given as
= 6.0*1.7*10^3 W = 10,200 w
energy provided per hour is Q = 10,200 W *1*60*60 s = 3.67*10^7 J
THEREFORE we have V
336*10^6 V = 3.67*10^7 j
v = .109 m3
volume of water is 0.1092 m3
The expression of the electric flux is
Here,
Q = Total charge enclosed in the closed surface
= Permittivity due to free space
Rearranging to find the charge,
Replacing with our values we have finally
The charge enclosed by the box is 0.1684nC
The sign of the charge can be decided by using the direction of the flux. The charge enclosed by the cube can be calculated by using the electric flux and the permitivity of free space.
Answer:
The correct option is H
Explanation:
From the question we are told that
The index of refraction of coating is
The index of refraction of material is
Generally the condition for constructive for a thin film interference is mathematically represented
Here t represents the thickness
For minimum thickness m = 0
So
=>
