Answer: 
The woman's distance from the right end is 1.6m = (8-6.4)m. 
The principles of moments about a point or axis running through a point and summation of forces have been used to calculate the required variable. 
Principle of moments: the sun of clockwise moments must be equal to the sun of anticlockwise moments.
Also the sun of upward forces must be equal to the sun of downward forces.
Theses are the conditions for static equilibrium.

<span>So we want to know how did the planets form in the Solar system. So the current most accepted explanation is accretion. First the Sun formed, and what has left was a disk made out of gas and dust which later formed the planets trough attractive gravitational force.</span>
        
             
        
        
        
Work with your units:
1 watt-hour = 1 (joule/second) · (hour) = 1 (joule-hour / second) 
(1 joule-hour/sec) · (3600 sec/hour) = 3600 joules
So 1 watt-hour = 3,600 joules
 
        
             
        
        
        
Answer:
Current in outer circle will be 15.826 A
Explanation:
We have given number of turns in inner coil 
Radius of inner circle 
Current in the inner circle 
Number of turns in outer circle 
Radius of outer circle 
We have to find the current in outer circle so that net magnetic field will zero 
For net magnetic field current must be in opposite direction as in inner circle 
We know that magnetic field is given due to circular coil is given  by

For net magnetic field zero 

So
