Answer:
a) ∆x∆v = 5.78*10^-5
∆v = 1157.08 m/s
b) 4.32*10^{-11}
Explanation:
This problem can be addressed using Heisenberg's uncertainty principle, which is expressed as:
Where h represents Planck’s constant (6.62*10^-34 J s).
Assuming that the electron's mass remains the same, we proceed as follows:
Utilizing the electron's mass (9.61*10^-31 kg) and the uncertainty in position (50 nm), we can compute ∆x∆v and ∆v:
If we treat the electron like a classic particle, the time required to cross the channel is determined using the upper limit of the uncertainty in velocity:
According to the second law, heat, often called thermal energy, cannot be entirely turned into work.
The second statement is closely tied to this law.
We can conclude that some energy dissipates while some is used for work.
E) This planet has a greater diameter than any of the four terrestrial planets that orbit close to the Sun.
B) A substantial amount of rocky material accumulated to create a planet larger than Earth.
(Which two statements are the most accurate)
- A, C, and D simply do not make sense.
Answer:
The primary factors that influence the intensity of shaking during an earthquake include the depth of the quake, its distance from the fault line, the type of soil below, and specifics about the buildings—especially their height. We will focus on the last two (soil quality and structures) and their interaction.
The energy contained in a photon is determined by the formula:
where h represents the Planck constant and f signifies the frequency of the photon. Given the energy of the photon,
, we can rearrange the equation to deduce the photon's frequency:
Now, we can use the relationship that links frequency f, wavelength
, and the speed of light c to ascertain the wavelength of the photon:
