Answer:
Taking it was dropped with inital velocity of 0m/s.
v = u+at
v = 0 + 9.8*1.5
v = 14.7s
(a=9.8m/s^2 << That's the acceleration due to gravity)
Explanation:
1.5 / 0.5 = 3 I believe this is the right answer
They share electrons because it is a covalent bond
Answer:
Self inductance, 
Explanation:
It is given that,
Length of the coil, l = 5 cm = 0.05 m
Area of cross section of the coil, 
Number of turns in the coil, N = 130
The self inductance relates the magnetic flux linkage to the current through the coil and it is given by :


L = 0.000127 Henry
or

So, the self inductance of the coil is 127 microhenry. Hence, this is the required solution.
