The force F between 2 objects is inversely proportional to the square of the distance, d between them. The force is 0.36 newtons
LenaWriter [7]

Answer:

0.73 N to 2 dp.

Step-by-step explanation:

F = k/d^2   where k is a constant , F = force and d = distance.

Substituting:

0.36 = k / (6)^2

k = 36*0.36 = 12.96 s the equation is F = 12.96 / d^2.

When d = 4.2 :

F = 12.96 / 4.2^2

F = 0.73 Newtons to 2 dp.

Write the standard form of the equation of the circle with the given characteristics.
SOVA2 [1]
<h2><u>Circle Equations</u></h2>

<h3>Write the standard form of the equation of the circle with the given characteristics.</h3><h3>Center: (0, 0); Radius: 2</h3>

To determine the equation of a circle, use the standard form of a circle (x - h)² + (y - k)² = r² where,

  • <u>(h, k)</u> is the center; and
  • <u>r</u> is the radius

Substitute the values of the center and radius to the standard form.

<u>Given:</u>

<u>(0, 0)</u> - <u>center</u>

<u>2</u> - <u>radius</u>

  • (x - h)² + (y - k)² = 2²
  • (x - 0)² + (y - 0)² = 4
  • x² + y² = 4

<u>Answer:</u>

  • The equation of the circle is <u>x² + y² = 4</u>.

igomit [66]

Solution:

The three powers whose value is greater than 500 and less than 550 can be find by following procedure.

We will solve this problem by Hit and trial method by finding the squares, cubes, fourth power, Fifth Power,...etc. of different natural numbers.

23²= 529

8³ = 8 × 8 × 8 =512

2^8=512

The three powers are →→→Eighth power of 2, Square of 23, and Cube of 8.

If 3a = cosec x and 3/a = cot x, find the value of 3(a2 - 1/a2)​
insens350 [35]

\csc(x) =  \frac{r}{y}  =  \frac{3a}{1} \\  \cot(x)  =  \frac{x}{y}  =  \frac{3}{a} \\ y = a = 1   \\  \\ 3( {a}^{2} - \frac{1}{{a}^{2} } ) \\   3( {1}^{2}  -  \frac{1}{ {1}^{2} } ) \\  = 0
