Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
Answer:
The smallest distance the student that the student could be possibly be from the starting point is 6.5 meters.
Explanation:
For 2 quantities A and B represented as
and 
The sum is represented as
For the the values given to us the sum is calculated as
Now the since the uncertainity inthe sum is 
The closest possible distance at which the student can be is obtained by taking the negative sign in the uncertainity
Thus closest distance equals 
meters
A, because Antoine came to a conclusion that it must have rained based on his visuals.
Answer:
triple covalent bond
Explanation:
A triple covalent bond is formed when three pairs of electrons (six electrons) are shared between the two combining atoms. A triple bond is shown by marking three short lines between the two symbols of the atoms. It requires three more electrons to attain the stable octet.

Answer:
Explanation:
The head decelerates from 4 m /s to zero in .2 sec so deceleration = 4 - 0 / .2
= 20 m/s²
If F be the average force acting on head
F - mg = ma
F = m ( g + a )
= 65 ( 9.8 + 20 )
= 1937 N .
This force will be uniformly acting on head in upward direction . So during first half and second half , deceleration is same hence force F will also be same .
