What is the least possible initial kinetic energy kmin the oxygen atom could have and still excite the cesium atom?

1 answer:

5 0

If perfectly elastic there would be no energy left over for exciting the atom. if the collision were partially elastic, then some of the initial kinetic energy would be converted into internal energy,

hope this help

An ocean wave traveling in one direction has a wavelength of 1.0 m and a frequency of 1.25 Hz. Take the direction of wave propag

aliina [53]

Answer:

a) $v=1*1.25=1.25\: m/s$

b) $y(x,t)=2sin(2\pi( x-1.25 t)$

c) $y(3,10)=1.73 m$

Explanation:

a) The speed of a wave is given by the following equation:

$v=\lambda f$

Where:

λ is the wavelength

f is the frequency

$v=1*1.25=1.25\: m/s$

b) The harmonic wave has the following equation:

$y=Asin(kx-\omega t)$

A is the amplitude (2 m)

k is the wavenumber (2π/λ)

ω is the angular frequency (2πf)

$y(x,t)=2sin(2\pi x-2\pi*1.25 t)$

$y(x,t)=2sin(2\pi( x-1.25 t)$

c) Here we need to find the heigth at x=3 m and t =10 s, so we need to find y(3,10).

$y(3,10)=2sin(2\pi(3-1.25*10)$

$y(3,10)=1.73 m$

I hope it helps you!

jeyben [28]

<h3><u>Answer and explanation;</u></h3>

<em><u>Sound waves are mechanical waves and are examples of the longitudinal type, a longitudinal wave involves the movement of molecules in the medium parallel to the direction of the wave.</u></em>
Sound waves are longitudinal mechanical waves because they move particles parallel to their direction of travel. For example, if a sound wave travels from left to right.
<em><u>Pitch is what we perceive as the low or high note quality of a sound. Pitch is determined by the frequency of the sound wave that moved through the air to our eardrums. Frequency is the time taken for a complete oscillation of a wave. </u></em>
The more energy or work used to create the vibration, which in turn creates the sound wave, the greater the amplitude of the wave and the louder the sound. Wavelength is the distance between two successive rarefactions or compression in a longitudinal wave.
For example, if you were to lightly hit a drum with a drum stick, there would be a softer sound as opposed to the loud boom that would be created if you hit the drum with all of your might

icang [17]

During primary second stage underwater recovery, it is acceptable to switch to your alternate air source while you search for your primary which makes it a true statement.

<h3>What is Primary second stage underwater?</h3>

This involves the intermediate pressure air from the regulator hose being taken and reduced to ambient pressure.

Switching to your alternate air source will ensure that the diver breathe safely which is why True was chosen.
