Answer:
giants has a higher luminosity
Explanation:
A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.Giant stars have radii up to a few hundred times the Sun and luminosity between 10 and a few thousand times that of the Sun.
While a white dwarf is a small, very dense, hot star that is made mostly of carbon. These faint stars(less luminous) are what remains after a red giant star loses its outer layers. Their nuclear cores are depleted. They are about the size of the Earth (but tremendously heavier)
<span>Right-hand rule reveals a connection between the current and the magnetic field lines in the magnetic field. It is also called Ampere`s right hand screw rule. It determines the direction of the magnetic field surrounding a current carrying wire. The thunb points direction of current and fingers point the direction of magnetic lines of force. Answer: C ) a counterclockwise rotation.</span>
