When the particle moves, its velocity is

When calculating scattering cross sections in particle physics, the interaction between particles can be described by starting from a free field which describes the incoming and outgoing particles, and including an interaction Hamiltonian to describe how the particles deflect one another.

When a particle falls into a black hole, it is boosted relative to an outside observer, and its gravitational field assumes a universal form.

; Quantum mechanics or Particle physics: When a spinless particle ( or even an unpolarized particle with spin ) decays, the resulting decay distribution must be isotropic in the rest frame of the decaying particle regardless of the detailed physics of the decay.

When this particle is absent, the infinitive is said to be a bare infinitive ; when it is present, it is generally considered to be a part of the infinitive, then known as the full infinitive ( or to-infinitive ), and there is a controversy about whether it should be separated from the main word of the infinitive ( see Split infinitive ).

When we perform the experiment, the probability of obtaining two particles in the state is now 0. 33 ; the probability of obtaining two particles in the state is 0. 33 ; and the probability of obtaining one particle in the state and the other in the state is 0. 33.

When we perform the experiment, we inevitably find that one particle is in the state and the other is in the state.

When a charged particle moves through a magnetic field B, it feels a Lorentz force F given by the cross product:

When it was found in 1900 by Max Planck that the energy of waves could be described as consisting of small packets or " quanta ", Albert Einstein further developed this idea to show that an electromagnetic wave such as light could be described as a particle ( later called the photon ) with a discrete quantum of energy that was dependent on its frequency.

When one measures the position of the particle, it is impossible to predict with certainty the result.

When a ( positive ) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles.

When a particle is on the outside of the center on one of the curved sections, by the time it flows through the straight area and into the other curved section it is now on the inside of center.

When the force on the far particle is subtracted from the force on the near particle, this first term cancels, as do all other even-order terms.

When first discovered, particle diffraction was a source of great puzzlement.

When passing through matter, a beta particle is decelerated by electromagnetic interactions and may give off bremsstrahlung x-rays.

:: When sand-sized particles are deposited, the space between the sand grains either remains open or is filled with mud ( silt and / or clay sized particle ).

When Einstein published his seminal 1905 paper on the particle theory of light, Millikan was convinced that it had to be wrong, because of the vast body of evidence that had already shown that light was a wave.

When we see the particle detectors flash or hear the click of a Geiger counter then Everett's theory interprets this as our wavefunction responding to changes in the detector's wavefunction, which is responding in turn to the passage of another wavefunction ( which we think of as a " particle ", but is actually just another wave-packet ).

When an object rotates about its axis, the motion cannot simply be analyzed as a particle, since in circular motion it undergoes a changing velocity and acceleration at any time ( t ).

When the partial pressure of is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate ( carbonate, bicarbonate, carbon dioxide, and carbonic acid ) shifts until the concentration of in the solution is equal to the solubility of CO < sub > 2 </ sub > at that temperature and pressure.

When pH is too high, the concentration of hydrogen ions in the blood is too low, so the kidneys excrete bicarbonate ( HCO < sub > 3 </ sub >< sup >−</ sup >).

When two miscible liquids are brought into contact, and diffusion takes place, the macroscopic ( or average ) concentration

When inspired air contains CO levels as low as 0. 02 %, headache and nausea occur ; if the CO concentration is increased to 0. 1 %, unconsciousness will follow.

When the hailstone moves into an area with a high concentration of water droplets, it captures the latter and acquires a translucent layer.

When it is present at a much higher concentration, it also binds to OR3, inhibiting transcription from P < sub > RM </ sub >, thus regulating its own levels in a negative feedback loop.

( ii ) When concentration of the ions is very high, the presence of charges on the ions appreciably effects the equilibrium.

When they encounter an infection site the particles gain a positive charge provoked by the slightly acidic environment at the infection sites, allowing them to bind to the negatively charged bacterial cell walls and release antibiotics at locally high concentration.

When probenecid and penicillin are administered together, probenecid competitively inhibits the excretion of penicillin, increasing penicillin's concentration and prolonging its activity.

When a neurotransmitter is released at a synapse, it reaches its highest concentration inside the narrow space of the synaptic cleft, but some of it is certain to diffuse away before being reabsorbed or broken down.

When the endpoint of the reaction is reached, the volume of reactant consumed is measured and used to calculate the concentration of analyte by

When the diode is forward biased, the injected carrier concentration is typically several orders of magnitude higher than the intrinsic level carrier concentration.

When the Buchenwald camp was evacuated, the SS sent the male prisoners to other camps, and the five-hundred remaining women ( including one of the secret annexe members who lived with Anne Frank, " Mrs. van Daan ", real name Auguste van Pels ) were taken by train and on foot to the Theresienstadt concentration camp and ghetto in Protectorate of Bohemia and Moravia.

When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases, this is known as ketonemia.

When the product dissociates the concentration of B is equal to q / p times the concentration of A.

When Schultz, who is empathetic to the Jews, voices his objection to the pogrom, Hynkel denounces Schultz as a supporter of democracy and a traitor, and orders him placed in a concentration camp.

When the ghettos were liquidated his family was sent to the Auschwitz concentration camp.

They were, like those babies, nearly dead from hunger ..." When Field Marshal Montgomery wanted to allot each German citizen a guaranteed diet of only 1, 000 calories a day and justified this by referring to the fact that the prisoners of the Bergen-Belsen concentration camp had received only 800, Gollancz wrote about starvation in Germany, pointing out that many prisoners never even received 1, 000 calories.

When she refuses, he uses force: he breaks her concentration and terrifies her by throwing her out of the airplane, catching her with the airplane, and he uses this to kiss her.

When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid ( BHB ), and acetone, is what is detected.

When people speak of a high-energy phosphate pool, they speak of the total concentration of these compounds with these high-energy bonds.

When performing calculations regarding the reacting of one or more aqueous solutions, one generally must know the concentration, or molarity, of the aqueous solutions.

When the oceans contain a relatively high proportion of magnesium compared to calcium, aragonite is more stable, but as the magnesium concentration drops, it becomes less stable, hence harder to incorporate into an exoskeleton, as it will tend to dissolve.
