Потребители с сопротивлением 4 Ом и 12 Ом соединены параллельно. Какая мощность (Вт) выделяется вторым потребителем, если первым выделяется мощность, равная 3,6 Вт?​

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)

Area around a charged object where the objects can exert a force on another charged objects is an electric
