Is the EARTH flat or round? really deep question don't make fun of it cuz there are too many contradiction
suter [353]

Answer:

Round

Explanation:

The Earth is round ,even though there are many contradictions. The Earth spins on an axis, which is why there are different time zones all around the world. If the world was flat, then an Earth's core wouldn't exist and also the laws of gravity would not make since due to the Earth being considered flat. People would never know if they met the end of the Earth, or if they walked off the face of the Earth. Also note that if the Earth was flat then our Solar System would have to be flat since it involves the planets to revolve around the Sun.

9.40_Q1) Which particle moves through a metal wire as electricity?
bija089 [108]

Answer No 1:

The correct option is Electrons.

Electrons are the negatively charged particles of an atom. They revolve around the nucleus of an atom. In circuits, electricity is carried by the electrons which move through a wire. Hence, option C is the correct option.

Other options like option A are not correct because protons are the positively charged particles of an atom. They are present in the nucleus of an atom and hence, do not generate an electric current.

Answer No 2:

Electrons move through the circuit from the negative power terminal to the positive power terminal.

Electrons make up the negative charged particles of an atom. They are involved in the conduction of electricity in circuits. In a circuit, the current flows from a negatively powered terminal to a positively charged terminal. This is known as the electron flow. Hence, option A is correct.

Answer No 3:

The correct option is B) Current

The movement or flow of electrons or electric charge is termed as electric current.  Whenever a circuit is completed, current is generated.

Other options like option C, resistance are not correct because resistance is the force which opposes current flow.

Answer No 4:

The correct option is A) Voltage

Voltage can be described as the force which causes electricity to flow in a circuit. Hence, option A is correct.

Other options like option C are jot correct because resistance is the force which opposes the flow of current.

Answer No 5:

The correct option is C) resistance

Resistance can be described as the force which opposes the flow of current. Resistance can be measured in ohms. It can be described as the difficulty which electrons have in moving through a circuit.

Other option like option A is not correct because voltage is the force through which current is generated.

Answer No 6:

The correct option is C amps

The S.I unit through which current is measured is called amperes. The symbol for amperes is A.  Hence, option C is the correct option.

Other options like ohms are not correct because ohms is the S.i unit for resistance.

Answer No 7:

The correct option is A) volts

The S.I unit for voltage is volts. Voltage can be described as the potential difference which is present in a circuit. Hence, option A is correct.

Other options are not correct because amp is the unit of electric current and ohms is the unit for resistance.

Answer no 8:

The correct option is C) ohms

In physics, resistance can be described as the force which opposes the motion of electrons or electrical current. The S.I unit for resistance is ohms. Hence, option C is correct.

Other options like option A is not correct because volts is the S.I unit of velocity. Option B is not correct because amps is the unit for electric current.    

Answer No 9:

The correct option is C) The voltage is decreased because of the electrical resistance.

According to ohm's law electric current is directly proportional to electric current and inversely proportional to electric resistance.

So, when the resistance increases, the voltage decreases.
