Asmall sphere of mass m = 0.32 g that carries a charge of q = 9.5 × 10−10 c. the sphere is attached to one end of a very thin silk string of length l = 8.75 cm. the other end of the string is attached to a large vertical conducting plate that has a charge density of σ = 30 × 10−6 c/m2. what is the angle that the string makes with the vertical?

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
