Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.
Explanation:
In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.
Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.
2. Is work the same as power?
Explanation:
The total energy of an aircraft flying in the atmosphere can be calculated using equation 1. [2]
E = ½ m v2 + mgh
A Boeing 737-300 has a maximum takeoff weight of 5.65 × 104 kg, a cruise altitude of h = 10,195 m, and cruise speed of 221 m/sec. Inserting these numbers into the above equation, we obtain 7.03 GJ for the energy at cruise conditions. [3] However, the engines mounted onto the wings of the plane are required to provide additional energy per time, power, in order to keep the aircraft flying at a constant altitude and speed
Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.
Protons and electrons are the two equally abundant particles in an atom.
The atom's nucleus contains protons, which are subatomic particles with a positive charge. A +1 positive electric charge permeates each proton.
An atom's nucleus is surrounded by electrons, which are subatomic particles with a negative charge. An electric charge of -1 is carried by each electron.
The number of protons in the nucleus of a neutral atom is equal to the number of electrons encircling the nucleus. The atom becomes electrically neutral when the balance of positive and negative charges results in a net electric charge of zero.
An atom with the atomic number 6 for carbon, for instance, contains six protons and six electrons. Similar to this, an atom of sodium, which has an atomic number of 11, contains 11 protons and 11 electrons.
An atom is stable and maintains its distinctive chemical properties because it has an equal number of protons and electrons.

b. Earth is an electromagnet.
c. A magnet always has a north pol, and may or may not also have a south pole.
d. Permanent magnets can be turned off.
The answer would be B. Earth is an electromagnet.
The Earth is a giant electromagnet. It's electromagnetic field is generated from the currents of electricity coming from molten metal flowing in the outer core of our Earth. The heat from the inner core causes convection and that is how electric current flows within Earth.
Earth us an electromagnet (apex)
B. less than
C. the same as
D. none of the above
The gravitational forces are the same. (C).
1 kg is 1 kg. It always has the same weight, no matter whether it's made of kryptonite, concrete, or chicken soup.
If I sealed the kg of lead and the kg of marshmallows into two different boxes, you couldn't tell any difference.
