I just googled refraction vs reflection. Hope this helps! :)
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)
Answer:
i really thought that said hater
Answer:
Explanation:
Capacitance is defined as the charge divided in voltage.
Introducing a dielectric into a parallel plate capacitor decreases its electric field. Therefore, the voltage decreases, as follows:
Where k is the dielectric constant and the voltage of the capacitor without a dielectric
The capacitance with a dielectric between the capacitor plates is given by:
Where k is the dielectric constant and the capacitance of the capacitor without a dielectric. So, we have:
Therefore, a capacitor with a dielectric stores the same charge as one without a dielectric.
