As an object's mass and the energy difference between it and the barrier's energy increase, the probability that it will tunnel through the barrier diminishes.

And although while the functionality shows that the wave function never fully hits zero, this explains why tunneling is common at the nanoscale but insignificant at the larger scale. The probability of tunneling declines exponentially with the square root of the mass of the particle (smaller particles may more easily tunnel through barriers than larger ones) and the barrier thickness.

Three requirements must be satisfied for a quantum particle to appreciably tunnel through a barrier ,

When reflected across a line of symmetry, a shape having that line of symmetry will fall on itself. These are the actual claims:

(1) The rectangle's diagonals will line up exactly with one another.

(2) A rectangle's diagonals are symmetry lines.

We deduce from the question that the rectangle is mirrored across the symmetry line.

When done, the rectangle's half will fall directly on the other half.

This indicates that the rectangle's diagonal will line up perfectly with the opposite diagonal.

According to the aforementioned claim, a rectangle's diagonal is also its line of symmetry.

Hello,

I hope you and your family are doing well!

To find the total area of all four walls of the room, you need to find the area of each wall separately and then add them all together. The area of a wall is the product of its height and width.

The width of each wall is 50 meters, and the height of each wall is 10 meters, so the area of each wall is 50 * 10 = 500 square meters. There are four walls in the room, so the total area of all four walls is 500 * 4 = 2000 square meters.

Answer: n= 1

Step-by-step explanation:

8n+7=-4n+19

First, subtract 7 from both sides

8n = 4n +12

Then add 4n from both sides

12n = 12

Then divide by 12 from both sides

n= 1

If you can please give me a Brainliest, thank you!

Answer: n = 1

Step-by-step explanation:

First, you could start off by bringing the -4n to the left side:

8n + 7 = -4n+19  →  12n + 7 = 19

Next, you take the 7 on the left side of the equals sign and subtract it from the 19:

12n + 7 = 19 → 12n = 12

Finally, you divide the 12 on the right by the 12 on the left:

12n = 12  →  n = 12/12

A number over itself will always be 1, so n = 1.

a) Using a system of equations, the amount invested in the mutual fund that earned 6% was $1,600.

b) The amount invested in the mutual fund that earned 4% was $200.

A system of equations is two or more equations solved concurrently.

A system of equations is also called simultaneous equations.

Total investment = $1,800

Profit from investment A = 6%

Profit from investment B = 4%

The total investment profit = $76

Let A = Investment A and B = Investment B

Answer: The expression you provided is a quadratic function in the form of H(x) = ax^2 + bx + c, where a = -7, b = 10, and c = -5. The graph of this function is a parabola with the vertex located at x = -b/2a = -10/(-14) = 5/7. The y-coordinate of the vertex can be found by plugging the x-coordinate into the original function, giving us H(5/7) = (-7)(5/7)^2 + 10(5/7) - 5 = -5/7 + 25/7 - 5 = 0. This means that the vertex of the parabola is located at the point (5/7, 0). The general form of the quadratic function is H(x) = -7(x - 5/7)^2.

A = -x² + 20 is a quadratic function in standard form that depicts each area as a function of width.

A quadratic in mathematics is a particular kind of problem that involves squaring, or multiplying a variable by itself. This terminology comes from the fact that a square's area equals the product of its side length and itself. Quadratum, the Greek word meaning square, is where the word "quadratic" originates.

Now, give the x and y labels to the two sides.

We are aware that a rectangle's area is;

A = length * width

Thus;

A = xy

Given that she has 40 feet of fencing, the following follows:

y = 0.5(40) - x

y = 20 - x

Consequently, the area in the quadratic function formula is;

A = x(20 - x)

A = 20x - x²

A = -x² + 20

If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, then each missing measure fm=88 and ce=44.

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.

Step 1: Identify each vertex's coordinates.

Step 2: Add together and divide by three all the x values from the coordinates of the three vertices.

Step 3: Add together all the y values from the three vertices and divide the result by three.

Step 4: The centroid coordinate is determined from the values collected in stages 2 and 3.

the ratio of both segments is 2:1.

where;

am = 44 and dm = 23

the longer segment is double of shorter one:

2*23 = 46.

Therefore,

fm = 46-23

By applying the exterior angle of a triangle theorem, m<WUV = 19°

What is an exterior angle of a triangle?

The angle created by one side of a triangle and the subsequently extended side is known as the external angle of a triangle. A triangle has three exterior angles, and the sum of those three external angles is always 360 degrees.

Here, we have

The given parameters are;

ΔUVW with side UW extended to X

m∠UVW = (x + 19)°

m∠VWX = (5x +14)°

m∠WUV = (x + 13)°

Applying the exterior angle of a triangle theorem:

m∠WUV + m∠UVW = m∠VWX

(x + 13)° + (x + 19)° = (5x +14)°

2x + 32 = 5x + 14

32 - 14 = 5x - 2x

18 = 3x

x = 6°

Now, we put the value of x in m∠WUV = (x + 13)° and we get

m∠WUV = (6+13)°

m∠WUV = 19°
