Alarge capacitor has a charge +q on one plate and - q on the other. at time t=0, the capacitor is connected in series to two ammeters and a light bulb. immediately after the circuit is closed, the ammeterconnected to the positive plate of the capacitor reads and the ammeter connected to the
each ammeter reads positive if current flows through thecircuit in a clockwise direction (from the + to the -terminal of the meter).
immediately after time t=0, what happens to the charge on the capacitor plates?
check all that apply.
individualcharges flow through the circuit from the positive to the negativeplate of the capacitor.
individualcharges flow through the circuit from the negative to the positiveplate of the capacitor.
the positiveand negative charges attract each other, so they stay in thecapacitor.
currentflows clockwise through the circuit.
currentflows counterclockwise through the circuit.
at any given instant after t=0, what is the relationship between the currentflowing through the two ammeters, and , and the current through the bulb,
what is the relationship between the current and charge? as the charge q(t) on the positive plate of the capacitor decreases, what happens to the value of the current?
the current
increases.
decreases.
does not change.

Ответ:
(conventional) current flows clockwise (positive to negative)
Ip = Ib = In
Q (charge) = I*t (current*time)
less charge = less current
Ответ:
Strong Nuclear force: it is the short range force and strongest fundamental force in all type of forces.
Electromagnetism: this is the force due to magnetic and electric behavior of the particles. It is moderate type of force and its range is more than Nuclear force.
Weak Nuclear Force: This force is also short range force which act between the nucleoside. But this force is also moderate type of force
Gravitational force: this force is between two point masses and least order of force. also the range of this force is upto infinite.
so the correct order of this fundamental force is
strong nuclear, electromagnetism, weak nuclear, gravitational
