The basic principles that apply to circuits is that electrons must receive energy from a source, and electrons transfer energy to perform some useful function.
<h3 /><h3>What is circuit?</h3>
Individual electronic components, like resistors, transistors, are connected by metallic wires or traces by which the electric current can flow to form a circuit design.
The basic principles that apply to circuits will be;
1. Electrons must receive energy from a source.
2. Electrons transfer energy to perform some useful function.
Hence, option 1 and 2 are correct.

In the outer layers of earths atmosphere gases are in ionized state primarily on account of cosmic rays . as earth rotates , strong electric current are set up due to movement of ions . these currents form earth magnetic field . and thus two equal and opposite poles of earth formed
Answer:
Explanation:
given,
side of square loop = a = 2.10 cm
Resistance of the wire = 1.30×10⁻² Ω
Length of the loop = c = 1.10 cm
rate of increasing current = 130 A/s
The average speed is 42.7 m/s
Explanation:
The speed of an object in uniform motion (=moving at constant speed) is given by the equation:
where
v is the speed
d is the distance
t is the time
For the car in this problem, we have:
d = 2560 m (distance)
t = 60 s (time)
Solving the equation, we find the average speed:

The object in the lower orbit will move faster in its orbit, and will have a shorter orbital period. None of that depends on their masses either.
