I'm giving you a general formula , its called ohm law it states that <span>electric current is proportional to voltage and inversely proportional to resistance
if V=voltage associated with the battery
R=resistance , I=current then
</span>
![\boxed{V=I*R}](https://tex.z-dn.net/?f=%5Cboxed%7BV%3DI%2AR%7D)

They lack a cell nucleus.
Answer: object B is negatively charged, object C is positively charged and object D is also positively charged
Explanation: since unlike charges attract and like charges repel, for object A which is positively charged and B to attract B must be negatively charged and then for B which is negatively charged and C to attract C must be positively charged and for C and D to repel they have to be of thesame charge which means D is positive as well.
Answer:
The magnitude of the flux of electric field through a square of surface area is zero.
Explanation:
![E=100 NC^{-1}\\\\A=2 m^2\\\\Electic\,\,flux\,\,flux\,\,is\,\,given\,\,as:\\\\\phi_E=E.A\,cos\,\theta](https://tex.z-dn.net/?f=E%3D100%20NC%5E%7B-1%7D%5C%5C%5C%5CA%3D2%20m%5E2%5C%5C%5C%5CElectic%5C%2C%5C%2Cflux%5C%2C%5C%2Cflux%5C%2C%5C%2Cis%5C%2C%5C%2Cgiven%5C%2C%5C%2Cas%3A%5C%5C%5C%5C%5Cphi_E%3DE.A%5C%2Ccos%5C%2C%5Ctheta)
It is given that square box is parallel to yz-plane which has normal vector perpendicular to plane in x-direction. Angle between normal vector of area and electric field is 90°. Substituting in (1)
![\phi_E=E.A\,cos\,(90^o)\\\\\phi_E=0](https://tex.z-dn.net/?f=%5Cphi_E%3DE.A%5C%2Ccos%5C%2C%2890%5Eo%29%5C%5C%5C%5C%5Cphi_E%3D0)
