The answer is c because:
Work done =force x distance
1)the edges where two plates meet are plate boundaries.
2)a sudden slip on a fault triggers an earthquake as stress in the edge overcomes the tension that releases energy into waves that move through the surface of the earth and cause a shake.
3)motion of the ground, aftershocks, shuddering, trembling, wobbling, crashing, falling, breaking, and more
4) the outer layer of Earth is the crust (lithosphere) which is made up of hot molten rock and granite.
Answer:
hydrophilic
Explanation:
hydrophobic means it hates water so a hydrophobic material would separate from the water and just sit there (an example of this is oil)
Answer:
See explanation
Explanation:
To find out the electronic structure of each element, you must know the number of electrons it contains.
If you find that out(the number of electrons in the neutral atom of an element is the same as its atomic number). Then you arrange those electrons in such a way that the first shell has only two electrons and subsequent shells have eight electrons.
Look up the groups to which the elements belong in the periodic table All the elements are in group 1 so the last shell must have only one electron.
Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.
Displacement:
It is a vector quantity that is defined as the overall change in the position of the object.
The formula for displacement is:
Where,
- total displacement
- final position
- initial position
In the given graph:
- Car displaces 15 km in 2 hrs
- Car displaces 20 km in 4 hrs.
- The car moves back to the initial position in 5 hrs.
Therefore, the displacement of the car in 5 hrs is 0 km.
