To understand the meaning of the variables in Gauss's law, and the conditions under which the law is applicable. Gauss's law is usually writtenΦE=∫ E. dA =qencl/ϵ0where ϵ0=8.85×10^−12C^2/(N⋅m^2) is the permittivity of vacuum. How should the integral in Gauss's law be evaluated?

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?
