Answer:
Explanation:
Rocks tell us a great deal about the Earth's history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.
Im pretty sure it’s A. temperature
Answer:
Point A is at higher potential than point B
Explanation:
Electrons are negatively charged - this means that they are attracted by positive charges and repelled by negative charges.
This also means that they tend to move in a direction opposite to the electric field lines (because electric field lines point away from a positive charge and toward a negative charge). So, they also tend to move from a point at lower potential to a point at higher potential.
In this problem, the electrons flow from point B to point A: therefore, point A must have higher potential than point B.

Answer:
16km/hr
Explanation:
Total distance travelled= 10km+6km
Time taken= 1 hour
As we know that,
Velocity = distance/time
So,
Velocity= 16km/hr
