a) to the right (East)
b) to the left (West)
c) up (rising)
d) down (setting).

I said A since it goes east to west, let me know, need help on this one

I go out for a walk. I first walk 1km north, then I walk 2 km west. Then I walk northwest ( an angle exactly between north and west) for 2 km. What is my displacement (magnitude and direction (direction means find the angle))? If I did this walk in 2 hours, what is my average velocity (magnitude) in meters per second?

This is a feeder Q.Could it be that what preceded was not a chemical event that caused the almighty explosion? Gregory Bateson suggests that thought came before an energy explosion.Was there something like a primordial energy that gave birth to elementary matter and fundamental particles from which arose what we now term as the Universe? And is it also possible that we hold it within us the secret of understanding the nature of the elemental advent? Thoughtful answers only. Thanks.
