Two metal spheres, each of radius 2.7 cm, have a center-to-center separation of 2.7 m. Sphere 1 has a charge of +1.1 × 10-8 C; sphere 2 has a charge of -2.9 × 10-8 C. Assume that the separation is large enough for us to assume that the charge on each sphere is uniformly distributed (the spheres do not affect each other). With V = 0 at infinity, calculate in volts (a) the potential at the point halfway between their centers and the potential on the surface of (b) sphere 1 and (c) sphere 2.

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

What does si stand for,when referring to a system of measurement

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
