a parallel-plate capacitor has a capacitance of 10 mf and is charged with a 20-v power supply. the power supply is then removed and a dielectric material of dielectric constant 4.0 is used to fill the space between the plates. what is the voltage now across the capacitor?

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
