Answer:
C
Explanation:
When trash accumulates, astronauts manually squeeze it into trash bags, temporarily storing almost two metric tons of it for relatively short durations, and then send it away in a departing commercial supply vehicle, which either returns it to Earth or incinerates it during reentry through the atmosphere.
Magnetic stripes on the sea floor
Explanation:
The observation of magnetic stripes patterns at the region of the Mid-Atlantic Ridge galvanized the evidence that sea floor spreading has been on for several millions of years.
- Geomagnetic field of the earth is similar to that of bar magnet having the north and south pole.
- It originates from the movement of iron-nickel within the outer core.
- This geomagnetic field causes the magnetization of magnetic minerals in rock.
- When freshly formed magma is brought to the surface at the mid oceanic ridge area, the prevailing magnetic field causes the magnetic minerals in the magma to cool in such a way that they align their domains to that of the field.
- The magnetic field of the earth can reverse and take different geometry. Sometimes, its intensity is very strong and at other times it is weak.
- The magnetic minerals in melts bear these records.
- As new materials are brought up, they get magnetized.

Answer:
0.275 nF
Explanation:
First of all, let's calculate the initial charge stored by the capactiro when it is in air. This is given by:
where
is the initial capacitance of the capacitor
is the voltage of the battery
Substituting, we find
When the Teflon slab is inserted between the plates, the capacitance changes according to:
where
is the dielectric constant of Teflon. Therefore, the new charge stored on the capacitor will be:
And so, the change in the charge on the capacitor is:
The electric field between the battery terminals.
