From the question we are told that:
Number of battery 
Voltage source
Lamp Power
Generally the equation for Resistance is mathematically given by



Therefore


Generally the equation for Current is mathematically given by



Answer:
Explanation:
(A) True: It is true.
In junction law, the current entering at a junction is equal to teh current leaving at the junction.
(B) False: It is false.
The kirchhoff's junction law is based on the conservation of charge.
(C) True: It is true.
Energy is used in the circuit.
(D) True: It is true.
It is based on the conservation of charge.
Answer:
in 1 second 3m, in 2 seconds 6m, in 3 seconds 9m.
Explanation:
distance=speed × time
Answer:
b. a large elliptical galaxy
Explanation:
In elliptical galaxies the stars are grouped in an elliptical shape, it has a low quantity of gas and dust in comparison to spiral galaxies, and its stars belong to an old population, there is not new stellar formation in it.
The stars orbit in a messy way which made to believe that they form from the merger of galaxies.
They are also really massive (around
solar masses).
The most massive and luminous can be found in the center of cluster of galaxies.
