The gravity has traditionally been defined as a force of attraction between things that have masses.
Explanation:
Gravitational force is a type of attractive force. It is because of this force, that we are able to walk on this Earth. Also due to gravitational force, the solar system and the galaxies are existing in the universe. Sir Issac Newton first discovered this force. He postulated the universal law of gravity. And according to this law, the gravitational force will be acting between the objects having masses and separated by a distance. So in this law, it states that gravitational law is directly proportional to the product of masses and inversely proportional to the square of the distance between them.
Thus, the gravity has traditionally been defined as a force of attraction between things that have masses.

B) The current passing through each bulb is the same.
C) By adding more light bulbs in the series, it will draw less current from the power source.
Eliminate
D) As more light bulbs are added in series, the brightness of the bulbs will stay the same.
Answers
Answer:
The correct answer is option b) "The current passing through each bulb is the same."
Explanation:
A series circuit is one where there is only one path for the current, from the power supply source through all the elements of the circuit, to return again to the source.
Because the current flowing through it only has one way to go, the same amount of current will be supplied at the same intensity throughout the circuit.
The equivalent or total resistance of the circuit is the sum of the resistances that compose it and will be greater than the greater of the resistances of the circuit. This means that as we add terminals (the devices connected to the power grid, which receive the current and transform it into another type of energy), the resistance increases.
Taking into account the definitions and characteristics above, the correct answer is option b) "The current passing through each bulb is the same."
It's B.
The current passing through each bulb is the same. As you add more light bulbs, the current will decrease in each, but it will always be the same current passing through each one.

B) 37 V
The potential difference between point a and point b is equal to 37 V
Explanation:
The potential difference across a and b can be calculated by finding the equivalent resistance of the resistors R1, R2 and R3 and then by applying Ohm's law.
Given:
R1 = 3.0 Ω
R2 = 8.0 Ω
R3 = 10.0
Current = I = 5 A
To calculate equivalent resistance of the circuit:
R2 and R3 are connected in parallel configuration. The equivalent resistance of R2 and R3 can be calculated as
Resistance R1 is in series with Rp. The equivalent series resistance is calculated as
Thus the given 3 resistor circuit can be written as an equivalent resistance Rs equal to 7.44 Ω through which current I passes.
By Ohm's law;
If V is the potential difference between a and b
Potential difference across points a and b = Current flowing through the circuit × Resistance between points a and b
37.2 V ≈ 37 V
Therefore, the potential difference between point a and point b is equal to 37 V
Answer:
Explanation:
37V
