Answer:

12 N

Explanation:

The concept of this question is based on Newton's third law

This law states that:

"For every action there is a reaction that is equal in magnitude but opposite in direction"

The equation representing this law is:

F₁₂ = -F₂₁

Now, for the given problem:

We have that the ball exerted a force of 12 N on the net

Applying the above law, the net would exert a force of equal magnitude and opposite direction to that of the ball

Therefore, the net will exert a force of 12 N on the ball

Hope this helps :)

If you use the first answer, the equation becomes 2x + 2y = 16. You could subtract this from equation Q to eliminate x.

The second answer makes equation P -2x - 2y = -16. You could add this to equation Q to eliminate x. You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.

The equation of a circle is (x + 6)^2 + (y - 4)^2 = 16. The point (-6, 8) is on the circle.

Answer:

y = 8 is the equation of tangent.

Step-by-step explanation:

The equation of the tangent to the circle at (-6,8) is of the form:

y = mx + c

where m is the slope of the tangent and c is the y-intercept.

The point (-6,8) lies on the circle and the tangent line as well.

Hence (-6,8) satisfies the line equation:

8 = m(-6) + c ⇒ c-6m = 8 -------------1

We know that slope of two perpendicular lines are related as:

$m_{1}\times m_{2}=-1$

At any point on the circle, the normal line at a point is always perpendicular to the tangent line at that point.

Hence :

$m_{normal} \times m_{tangent}=-1$

We can find the slope of the normal at point (-6,8) as it passes through the centre of the circle (-6,4) by using the two-points formula for slope.

$m=\frac{y_2-y_1}{x_2-x_1}$
