b) They are mostly negative.
c) They are close to zero.
d) They are mostly positive.
Answer: The correct option is (c).
Explanation:
The electric force exists between the charged particles only.
The electric force between the negatively or positively charged particles is attractive in nature while the electric force between the negative and the positive charged particles is repulsive in nature.
Matter consists of atoms. Atom consists of electrons, protons and neutrons. Only, electrons can move. If the atom loses electrons then matter gets negatively and positively charge respectively.
In the given problem, the matter is mostly neutral on a large scale. On a large scale, the electric forces are close to zero.
Therefore, the correct answer is (c).
The first satellite to capture a photograph of Earth from space was Explorer 1, launched on January 31, 1958. This and subsequent space missions like the Apollo program expanded our visual understanding and perception of our planet.
The first satellite to give us a photograph of the Earth from space was Explorer 1, launched on January 31, 1958. Prior to Explorer 1, the Soviet Union had launched Sputnik 1 in October 1957, but Explorer 1 was the first satellite to provide us with images of Earth from space. This marked a significant moment in human history, altering our perception of the planet.
Later on, the Apollo program further improved our visual understanding of Earth, with the Apollo 17 mission capturing the 'Blue Marble' - one of the rare full disk images of the Earth in sunlight. Such images underscored our perception of Earth as a small, yet interconnected and strikingly beautiful, celestial body floating in the vastness of space.

b. potentiometer
c. voltmeter
d. galvonmeter
e. batterymeter
The device used to measure a potential difference in a circuit is called a voltmeter. The correct option is c.
The tool used to measure the potential difference between two locations in an electric circuit is called a voltmeter. A voltage meter usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
Both of these devices are employed in electric circuits, however, the voltmeter is primarily used to measure the voltage or emf across two points in an electric circuit, whilst the ammeter is mostly used to measure the flow of current.
Depending on the measurement, voltmeters are divided into two categories: DC voltmeters and AC voltmeters.
Therefore, the correct option is c. voltmeter.
