Step-by-step explanation:
A) as you can see there is no current flowing in a bar magnet so (incorrect)
B) Lines of magnetic field is going in A-->B direction so it have starting and ending points.(incorrect)
C) Yes whenever a magnetic object is placed near the another magnetic object they either attract or repell so they have a force in a form of push and pull [correct]
D)No because magnetic field lines goes from North--> South so A is the South pole [ incorrect]
E) Yes it will point always towards North pole of the magnet [correct]
F) yes it depends upon the density of field lines[correct]
G)No the near the magnet is it becomes more stronger as compared to magnet kept far.(incorrect)
So option C E F are correct
Hope this helps
Have a great day
Therefore, the equation of circle is: 
<h3><u>
What is a circle?</u></h3>
- All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
- The radius of a circle is the separation between any point on the circle and its center.
- The radius must typically be a positive integer. Except when otherwise specified, this article discusses circles in Euclidean geometry, namely the Euclidean plane.
- A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior.
Here we know that
but we are not given the radius.
However, we can find the radius by using the distance formula.
, where 
and 
Putting the values, we get:
The radius comes out to be:
An equation of the circle with center 
and radius r is
Now, substituting the values, we get:
Therefore, the equation of circle is:

Answer:
10 times greater
Step-by-step explanation:
When you write these as numbers, you get:
800,000,000 (8 hundred million place)
80,000,000 (8 ten million place)
Then divide the greater number by the less number:
800,000,000/800,000,00
make this easier by eliminating 0's:
80<u>0,000,000</u>/8<u>0,000,000</u>
80/8
10
10 times greater is your answer
Hope this helps!
Answer:
Use, y = 3x-3, it might be easier to graph
Step-by-step explanation:
You can convert this equation into slope-intercept for to gramph.
y = (x – 3)2 + 3
y = 3x-6+3
y = 3x-3
40 over 100 and 55 over n cross multiply 55 x 100 and divide by 40.which gives you 137.5
