Answer:
I'm going to say b. gasoline is a chemical and when it combusts, it causes heat (thermal energy) and when the piston rotates because of the thermal expansion, you get mechanical force.
Charge is actually either excessive number or electrons or shortage of them.
as you can't destroy the electron or create it - you can't destroy or create charge
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.

Acceleration is a derived unit because it is derived from two quantities : Velocity and time.
We know, acceleration = Change in velocity/Time
