The separation between a 6.8 kg particle and a 3.7 kg particle in order for their gravitational attraction to have a magnitude of 2.9 ✕ 10^−12 N will be 24 m.

m₁ = 6.8 kg

m₂ = 3.7 kg

F = 2.9×10^−12 N

We want to determine the distance r between both particles. The gravitational force on particle 2 due to particle 1 has the same magnitude as the force on particle 1 but in the opposite direction. If a distance r separates two masses, then the magnitude of the gravitational force acting on each due to the presence of the other is given by

F = Gm₁m₂/r²     Eqn(1)

Where G is the gravitational constant and equals 6.6×10^−11 N⋅m²/kg².

By solving equation (1) for r, we get

r = √(Gm₁m₂/F)

Now we can plug our values for m₁, m₂ and G into equation (2) to get the separated distance r

r = √(Gm₁m₂/F)

= √{[(6.6×10^−11 N⋅m²/kg²)(6.8 kg)(3.7 kg)]/(2.9×10^−12 N)}

​= 24 m

The gravitational force is very small due to the small masses where this force is indistinguishable.

If the sequence is aₙ = n/2n²+1 then the process to show the sequence is monotone decreasing for n≥1 is shown below .

To show that the Sequence "aₙ = n/2n²+1"  is monotone decreasing for n ≥ 1, we need to prove that for any two consecutive terms of the sequence, the next is always less than or equal to the previous one .

Let's compare two consecutive terms of the sequence, aₙ and aₙ+1:

⇒ aₙ = n / 2n² + 1  

So , aₙ₊₁ = (n + 1)/2(n + 1)² + 1

we have to show that aₙ₊₁ ≤ aₙ, we can subtract aₙ from both sides:

⇒ aₙ₊₁ - aₙ = [(n + 1)/2(n + 1)² + 1] - [n/2n² + 1]  ;

We can simplify this expression and get ;

⇒ aₙ₊₁ - aₙ = (n+1-n)/2(n+1)²+(1-1)

⇒ aₙ₊₁ - aₙ = 1/2(n + 1)²

the fraction ,  1/2(n + 1)² > 0 for all n ≥ 1,
that means ⇒ aₙ₊₁ - aₙ > 0 ; ⇒  aₙ > aₙ₊₁ ;

Considering Moses Road is 7 kilometres long, then that would take Moses roughly 21 minutes and 30 seconds to make the route at his top speed of 21 kilometres per hour.

Speed is referred to as the rate at which an object's location changes in any direction. Speed is defined as the ratio of distance travelled to time spent travelling. Because it has just one direction and no scale, speed is a scalar number.

Step 1: Determine the total distance travelled (7 km)

Step 2: Determine how long it takes to traverse the distance (7 km/21 km/h = 0.333 h = 20 min).

Step 3: Accounting for the half km/h, add 30 seconds to the overall time (20 minutes + 0.5 minutes = 20.5 minutes).

Step 4: To the closest minute, round the total time (20.5 minutes = 21 minutes).

As a result, at the maximum speed of 21 km/h, Moses will finish the route in around 21 minutes.

positive value for a causes the fixed point to be unstable; a negative value for a makes it stable; and a value of zero places the fixed point at the origin and makes it stable On a graph.

The fixed point of the system occurs at x* = 3/a when an is positive. The system's eigenvalue is = a, while the system's Jacobian matrix is provided by J = [a]. The fixed point is said to be unstable if an is positive because small perturbations will cause larger departures from the fixed point. If an is positive, then is also positive. When an is low, the fixed point is stable and the eigenvalue is also low. The fixed point is at the origin (x* = 0) when an is zero and the eigenvalue is also zero. This indicates that the fixed point is stable and that the system won't deviate from its starting place. On a graph, the fixed point is at the origin if the slope is zero, unstable if the slope is positive, and stable if the slope is negative. Since positive slopes travel away from the fixed point and negative slopes go closer to the fixed point, the slope's sign reflects how stable the fixed point is. As a result, the fixed point is unstable if an is positive, stable if an is negative, and stable if an is zero, meaning the fixed point is at the origin.

If the length, width, and height of a right rectangular prism are halved, the surface area will be reduced by a factor of four.

The surface area of a right rectangular prism can be calculated by adding up the areas of all six of its faces.

To see why, consider that each of the original face's area was given by the product of two of the original dimensions. If each of those dimensions is halved, the area of each face is reduced to one-fourth of its original size. Because there are six faces, the total surface area is reduced by a factor of four.

In other words, if the original surface area was 2 * (44 cm * 22 cm + 44 cm * 77 cm + 22 cm * 77 cm) = 6176 square cm, the surface area of the halved rectangular prism would be 6176 square cm / 4 = 1544 square cm.

Answer:

So, Lake Erie is 3/8 the size of Lake Superior.

Step-by-step explanation:

To find the size of Lake Erie in comparison to Lake Superior, we need to first find the size of Lake Michigan in relation to Lake Superior. If Lake Michigan is about 7/8 the size of Lake Superior, we can say that:

Lake Michigan / Lake Superior = 7/8

Next, we need to find the size of Lake Erie in relation to Lake Michigan. If Lake Erie is about 3/7 the size of Lake Michigan, we can say that:

Lake Erie / Lake Michigan = 3/7

Now, we can use these two relationships to find the size of Lake Erie in relation to Lake Superior. To do this, we can cross-multiply and simplify:

Lake Erie / Lake Michigan = 3/7

(Lake Erie / Lake Michigan) * (Lake Michigan / Lake Superior) = (3/7) * (7/8)

Lake Erie / Lake Superior = (3/7) * (7/8) = 3/8

So, Lake Erie is 3/8 the size of Lake Superior.

The lines are perpendicular to each other because the graph of y = -6 is a horizontal line with a slope of 0, and the graph of x = 1/6 is a vertical line with a slope that is undefined.

A line's steepness may be determined by its slope. In measuring slopes mathematically, "rise over run" is being used (change in y divided by change in x).

The vertical difference between two places, known as the rise, and the horizontal difference between those same two points, known as the run, is known as the slope. It is referred to as the slope-intercept version of the equation if the equation of a line is expressed as y = mx + b. Slope is indicated by "m". And b is the value in the y-intercept point (0, b).

Given that cost of a company picnic varies directly as the number of employees attending the picnic

Let "c" be the company picnic cost

Let "n" be the number of employees attending the picnic

Therefore,

 cost ∝ number of employee attending picnic

   c = kn

Where "k" is the constant of proportionality

c = kn ---------- eqn 1

Given that company picnic costs $487.50 for 30 employees

Therefore substitute c = 487.50 and n = 30

   487.50 = k(30)

  k =   487.50/30

   k = 16.25

Substitute n = 80 and k = 16.25 in eqn 1
