Explanation:
Given that,
Distance between two long wires, d = 16 cm = 0.16 m
Current in one wire, 
Current in wire 2,
The magnetic force per unit length of one wire on the other is given by the following expression as :



The current is flowing in opposite direction, the magnetic force acting on it is repulsive. Hence, this is the required solution.
Gravitational acceleration (Ga) is inversely proportional to k / Distance^2
so Ga * Distance^2 = K
On the surface of Earth acceleration due to gravity is about 9.8m/s^2 with an average distance to the earths core of about 6371 km (Wolfram alpha).
So k = 9.8 * 6371^2
I'm presuming that your distance of 116 is km
As
Ga = k / distance^2
Ga = ((9.8 * 6371^2) / (6371 + 116)^2 ) = 397778481.8 / 42081169
= 9.45 m/s^2 to 2sf

2. Relative plate velocity.
Explanation:
Answer:30 cm
Explanation:
Given
object distance 
focal length of concave mirror 
height of object 
Using mirror formula




and magnification is



So height of object is same as of object .
Position :image is formed at the spot where object is placed.
