Abattery is used to drive a circuit, but after a certain amount of time, the current is zero. when the same circuit is driven by an ac generator, the current is non-zero and alternates. which combination of elements is most likely to comprise the circuit?

capacitors only

Explanation:

When a battery or a DC supply is used to drive a circuit, the current becomes zero after some time. But when an AC generator is used in the same circuit, the current is non-zero and is alternates.

Here, a combination of capacitors are used to drive the circuit.

As we know in capacitor,

current, i = c. dv/dt

where c is capacitance, v is voltage and t is time.

So as in DC voltage, v (voltage) is constant and hence current i = 0.

But in AC voltage, the voltage v varies with time t. Therefore here capacitors are used only.

Capacitors are used to store energy.

Thus the answer is capacitors.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !

answer: ‘no one should be discriminated against because he or she is not from a minority group’

because—> affirmative action means ‘a policy or program that provides opportunities for traditionally disadvantaged groups to them overcome the effects of discrimination’
