2 простых вопроса по напряженности поля и конденсатора

1. Выведите пожалуйста формулы для расчета поле внутри конденсатора и поля пластины поясните, чем поле внутри конденсатора отличается от поля пластины и почему?

2. Как Вы думаете, может ли проводник (конденсатор, например) копить заряд до бесконечности?

The dot diagram represents the motion of the motorcycle as it moves from left to right

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
