consider three identical metal spheres A, B, and C. Sphere A carries a charge of -2.0uC; sphere B carries a charge of -6.0uC; and sphere C carries a charge of +6.0uC. Spheres A and B are touched together and then separated. Spheres B and C are then touched and separated. What is the charge on sphere C?

J. j. thomson’s experiment disproved the theory that an atom

Select for each of the following statements whether it is correct or incorrect. (a) in an isothermal expansion of an ideal gas. (b) the temperature remains constant. (b) the pressure remains constant. (c) there is work done by the gas. (d) there is heat added to the gas. (e) the change in internal energy equals zero.

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.)
