there is 1000 grams in 1 kilogram
Divide
80/1000 = 0.08
0.08 kilograms is your answer
hope this helps
Friction force is when you rub 2 things together and they get warm. Motion, on the other hand, is if your walking along the sidewalk - you hardly get warmer -------
Unless it's a colder day outside and you're walking SO you decide to rub your hands together to get warm, but if you were just walking , its motion and only motion - no friction :):)

Answer:
(A). The flux is 0.336 N.m²/C
(B). The flux is zero.
Explanation:
Given that,
Length = 4.2 cm
Width = 4.0 cm
Electric field ![E=(150 i-200 k)\ N/C](https://tex.z-dn.net/?f=E%3D%28150%20i-200%20k%29%5C%20N%2FC)
Area vector is perpendicular to xy plane
(A). We need to calculate the flux
Using formula of flux
![\phi=E\cdot A](https://tex.z-dn.net/?f=%5Cphi%3DE%5Ccdot%20A)
Where, E = electric field
A = area
Put the value into the formula
![\phi=(150 i-200 k)\times(4.2\times10^{-2}\times4.0\times10^{-2})k](https://tex.z-dn.net/?f=%5Cphi%3D%28150%20i-200%20k%29%5Ctimes%284.2%5Ctimes10%5E%7B-2%7D%5Ctimes4.0%5Ctimes10%5E%7B-2%7D%29k)
![\phi=-200\times4.2\times10^{-2}\times4.0\times10^{-2}](https://tex.z-dn.net/?f=%5Cphi%3D-200%5Ctimes4.2%5Ctimes10%5E%7B-2%7D%5Ctimes4.0%5Ctimes10%5E%7B-2%7D)
![\phi=-0.336\ N.m^2/C](https://tex.z-dn.net/?f=%5Cphi%3D-0.336%5C%20N.m%5E2%2FC)
(B). Given electric field
![E=(150i-200j)\ N/C](https://tex.z-dn.net/?f=E%3D%28150i-200j%29%5C%20N%2FC)
We need to calculate the flux
Using formula of flux
![\phi=E\cdot A](https://tex.z-dn.net/?f=%5Cphi%3DE%5Ccdot%20A)
Put the value into the formula
![\phi=(150 i-200 j)\times(4.2\times10^{-2}\times4.0\times10^{-2})k](https://tex.z-dn.net/?f=%5Cphi%3D%28150%20i-200%20j%29%5Ctimes%284.2%5Ctimes10%5E%7B-2%7D%5Ctimes4.0%5Ctimes10%5E%7B-2%7D%29k)
Here, The component of k is not given
So, the flux is
![\phi=0](https://tex.z-dn.net/?f=%5Cphi%3D0)
Hence, (A). The flux is -0.336 N.m²/C
(B). The flux is zero.
