1000 millicoulombs of charge passes through a point. The amount of current passing through the point is

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

Describe the function of the endomembrane system? what organelles are involved?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
