An absolute zero is when all forms of being cease to move due to low to none existing thermal energy between all living things. It follows the statement of Kelvin’s temperature scale where the temperature is -275.15K or -546.3°C.
Answer:
5°
Explanation:
Two diverging light rays, originating from the same point, have an angle of 5° between them.
According to laws of reflection the angle of incidence is equal to the angle of reflection.
From the attached figure, it is clear that the after reflection from a plane mirror the angle between two rays will be 5°.
O be the originating point. m and n two diverging light rays. When they strikes at the plane mirror, the laws of reflection still fulfilled.
Answer:
B im pretty sure
Explanation:
B. a wire connected in a complete loop
C. a source of electrical energy
Answer: The correct answer is an electrical insulator.
Explanation:
Insulator : It is a material which resists the flow of electrons. It has high resistance in comparison to the conductor.
Conductor: It is a material which allows the flow of electrons. It has low resistance in comparison to the conductor.
Battery is a source of electrical energy. It forces the electrons to flow. The rate of flow of electrons constitutes the current.
In the given problem, an electrical insulator is not needed for a charge to flow through a conducting wire.
To design the circuit and to make a current flow in the circuit, a battery, a wire connected in a complete loop and a source of electrical energy are needed.
Therefore, the correct option is (C).
