Answer: 8
Explanation:
Non metals which have 4 electrons in the outer shell i.e in the valence shell bond with the other similar non metals having 4 electrons in their valence shell. This bond is known as covalent bond in which the two atoms share their valence electrons with each other in order to complete their valence shell. These atoms seeks to have 8 electrons in order to attain noble gas configuration.
Answer:
1) 
from the positive x-axis.
2) 
Explanation:
Given:
speed of rowing in still water, 
1)
speed of water stream, 
we know that the direction of resultant of the two vectors is given by:
where:
the angle of resultant vector from the positive x-axis.
angle between the given vectors
When the rower wants to reach at the opposite end then:
so,
from the positive x-axis.
2)
Now the resultant velocity of rowing in the stream:
Therefore time taken to cross a 4 miles wide river:
