How does conservation of energy apply to roller coasters?

1 answer:

3 0

Well in rollercoasts u have low points and high points. at the high points you have potential energy and at the low points you have kinetic energy, but the energy remains equal throughout.

Examine the total number of orbitals in the n = 1 through 4 shells. what is the relationship between the n value and the total n

Veseljchak [2.6K]

The total number of orbitals in the n = 1 through 4 shells is only 1.

The relationship between the n value and the total number of orbitals is given as

Total number of orbitals = n²

Because there is only one way a sphere can be orientated in space, there is only one(1) orbital in the n = 1 shell.

An orbital has n² total orbitals for a given value of n.

Each atom's electron is given one of four quantum numbers, the primary quantum number (symbolized n), to describe the state of that electron. It is a discrete variable since the values are all natural numbers starting at 1.

The orbital's size is defined by the primary quantum number (n). For example, orbitals with n = 2 are larger than those with n = 1.

Electrons are drawn to the atom's nucleus because their electrical charges are in opposition to one another.

In order to excite an electron from an orbital where it is close to the nucleus (n = 1) to an orbital where it is distant from the nucleus (n = 2), energy must be absorbed.

Thus, the energy of an orbital is indirectly described by the primary quantum number.

A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake.

Nataliya [291]

To solve the exercise it is necessary to take into account the definition of speed as a function of distance and time, and the speed of air in the sound, as well

$v=\frac{d}{t}$

Where,

V= Velocity

d= distance

t = time

Re-arrange the equation to find the distance we have,

d=vt

Replacing with our values

$d= (343)(3.7)$

$d= 1269.1m$

It is understood that the sound comes and goes across the entire lake therefore, the length of the lake is half the distance found, that is

$L_{lake} = \frac{d}{2}$

$L_{lake} = \frac{1269.1}{2}$

$L_{lake} = 634.55m$

Therefore the length of the lake is 634,55m

a central concept in quantum mechanics is that both matter and are alternate forms of the same entity and therefore both exhibit

Stels [109]

In quantum mechanics, a central concept is that both matter and energy are alternate forms of the same entity and therefore both exhibit dual characteristics of particles and of waves.

Matter can be defined as anything that has mass and is able to occupy space.

Thus, any physical object or substance that is found on Earth is typically composed of matter.

Similarly, energy is highly affected by the mass of a any physical object or substance just like matter,

Hence, both energy and matter are known to be made up of atoms and as a result of this fact, exhibit dual characteristics of particles and of waves.

A wave can be defined as a disturbance in a medium that progressively transports energy from a source location to another location without the transportation of matter.

In conclusion, this central concept makes it easier for us to better understand the behavior of tiny particles such as electrons.
