I think the answer should be the last one. Magnets attract magnets with unlike poles and repel magnets with like poles
The grains in igneous rocks are interlocking but the Metamorphic rocks are not.
Answer:

Explanation:
If we express all of the cordinates in their rectangular form we get:
A = (1404.77 , 655.06) m


Since we need C to be (0,0) we stablish that:

That way we make an equation system from both X and Y coordinates:


Replacing values:
With this system we can solve for both Db and Dc and get the answers to the question:


Answer:
Explanation:
Distance travelled = 600 - 500 = 100 m
Time taken = 9:03:25 a.m.- 9:03 :05 a.m.
= 20 s
average speed = distance / time taken
= 100 / 20 m /s
= 5 m /s
