A terain tarvels 120 I in 2 hours and 30 mins .what is its average speed

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.)

What organization and environment is described above?

Which is an example of an exothermic process?
