This question is off-base and misleading from the beginning.
When you jump off the Earth, your momentum changes, <em>and the Earth moves away from you with an equal change of momentum in the opposite direction</em>.
1). Momentum is conserved when you jump. But we don't feel the Earth moving. Since the Earth's mass is a bazillion times greater than YOUR mass, the speed with which the Earth moves away from you is only one bazillionth of your speed. That way, the product of (mass) x (speed) is the SAME for you and for the Earth, and momentum is conserved.
2). <em>Of course !</em> If everyone jumped at the same time, the Earth's momentum would change. In answer-(1), I explained that the Earth's momentum changes whenever <em>ONE PERSON</em> jumps. So 7 billion people all jumping at the same time would certainly make it change.
If basically means to move quickly
Answer:
So to increase current of the circuit what you can do is :
1. Use conductor of low resistivity, ¶.
2. Use conductor of small length.
3. Use thick wire.
4. Decrease the temperature of the circuit.
5. If operating temprature is high than use semiconductor, because it have negative temprature coefficient.
6. Minimise the circuit losses.
