The ratio 2:7. Add 7 and 2 together to get 9. Then divide 243 by 9 which is 27. 27x2 is 54 so. There was 54 students out of state. And 189 that were in state

Demonstrate that there is approximately 16% probability (P) of finding the ground state harmonic oscillator displaced beyond the
Misha Larkins [42]

Answer:

The probability of finding a particle in a space is proportional to the square of its absolute value.

In quantum mechanics, there are still chances of find a particle in a classically forbidden region.

That is, finding the ground state harmonic oscillator displaced beyond the classical turning points.

Since there is a chance for finding the ground state harmonic oscillator displaced beyond the classical turning points, the probability (P) will have a value and not equal to Zero( I.e 16%).

By normalization, the probability can be added to 1

This phenomenon is tunneling in quantum mechanics.

Step-by-step explanation:

The motion of a classical oscillator is confined to the region where its kinetic energy is nonnegative.

Physically, it means that a classical oscillator can never be found beyond its turning points, and its energy depends only on how far the turning points are from its equilibrium position. The energy of a classical oscillator changes in a continuous way. The lowest energy that a classical oscillator may have is zero, which corresponds to a situation where an object is at rest at its equilibrium position. The zero-energy state of a classical oscillator simply means no oscillations and no motion at all (a classical particle sitting at the bottom of the potential well.

Julie goes to the park across the street from her house several times a day and jogs a total of six miles every day. She jogs th
AleksandrR [38]

Answer:

The Divisor is 6 miles

Step-by-step explanation:

A Divisor is also defined as a number by which a another number called dividend is divided by with or without having a remainder.

Divisor ÷ Dividend = Quotient

We are told that Julie goes to the park and jogs a total of six miles every day. She jogs three-fourths of a mile at a time.

In 1 day = 6 miles

Spread throughout the day, or per time , Jules jogs 3/4 of a mile

To find out how many times she jogs in a day, 6 miles will be divided by 3/4

Divisor ÷ Dividend = Quotient

= 6 ÷ 3/4

= 8 times in a day.

Looking at the above, calculation, 6 miles is the Divisor.
