Alright, here we go.

The Doppler effect is an observation about the noticeable changes of a sound wave as the producer moves to and from an observer. If the producer is moving closer to an observer as the sound is being emitted, the observer will hear a higher-pitched noise than what the producer is making. Consequently, if the producer is moving away, the sound will be a lower pitch. This is a result of a decrease and increase in distance, distorting the observed sound by affecting the length of the wave.

In supporting the Big Bang theory, this observation deals with light being received from distant stars, and is instead called the redshift effect. The Big Bang theory supports the initial expansion of the universe from an infinitesimal singularity, followed by a continued inflation of the size of the universe. Edwin Hubble, developer of the modern telescope, first observed this phenomenon in 1912 in an effort to determine the physical size of the universe.

Similar to the Doppler effect, the redshift effect involves stars moving away from Earth as the universe expands; the increasing distance as stars emit light “stretches” the wavelength of the emitted light - when light is stretched, it moves from the violet end of the visible spectrum towards the red, hence the name.

Recall the principle of expansion tied to the BBT - certain lights observed from the outer reaches of the universe are great in magnitude, but their color doesn’t match what is expected. Large visible bursts are expected to be white and blue, as these are the only type of stars that can produce such a power; sometimes, however, they appear as red. This is a direct observance of the redshift effect, and a plain observation about the theory of the Big Bang.

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
