Given, the mass of the balls, m1 = 0.44 kg and m2 = 0.22 kg initial velocities, u1 = 3.30 m/s towards east and u2 = 0 m/s Let the velocities of m1 and m2 after the collision are v1 and v2 respectively. By the conservation of momentum, we get m1v1 + m2v2 = m1u1 + m2u2 or, 0.44v1+0.22v2= 0.44*3.3 + 0.22*0 or, v2 = 6.6-2v1 (1) And by the conservation of kinetic energy, we get 1/2∗m1v12+1/2∗m2v22=1/2∗m1u12 +0 or, m1v12+m2v22=m1u12 or, 0.44* v12 + 0.22* v22 = 4.7916 (2) Substituting the equation (1) to (2), we get 0.44* v12 + 0.22 (6.6−2v1)2 =...

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
