When the angular velocity of this co-rotating frame is not constant, that is, for non-circular orbits, other fictitious forces — the Coriolis force and the Euler force — will arise, but can be ignored since they will cancel each other, yielding a net zero acceleration transverse to the moving radial vector, as required by the starting assumption that the vector co-rotates with the planet.

When this field is instead studied using the QED vacuum of quantum electrodynamics, it is seen that the plates do affect the virtual photons which constitute the field, and generate a net force — either an attraction or a repulsion depending on the specific arrangement of the two plates.

When the group of covalently bound atoms bears a net charge, the group is referred to more properly as a polyatomic ion or a complex ion.

When light makes multiple reflections between two or more parallel surfaces, the multiple beams of light generally interfere with one another, resulting in net transmission and reflection amplitudes that depend on the light's wavelength.

When diamagnetic material is placed in a magnetic field, a magnetic dipole tends to align itself in opposed polarity to that field, thereby lowering the net field strength.

When the fish are old enough they are freed from the net to mature in the open sea.

When a magnetic field is applied, the dipoles will tend to align with the applied field, resulting in a net magnetic moment in the direction of the applied field.

When an external magnetic field is applied to an assembly of superparamagnetic nanoparticles, their magnetic moments tend to align along the applied field, leading to a net magnetization.

When the net force on the system is zero, the torque measured from any point in space is the same.

When using contracts, a supplier should not try to verify that the contract conditions are satisfied ; the general idea is that code should " fail hard ", with contract verification being the safety net.

When some other piece is chosen it is known as " underpromotion ", and the piece selected is most often a knight, used to execute a checkmate or a fork giving the player a net increase in material compared to promoting to a queen.

When net income is composed of large non-cash items it is considered low quality.

When the disk undergoes a full clockwise revolution, the bicycle wheel will not return to its original position, but will have undergone a net rotation of.

When the membrane is in thermodynamic equilibrium ( i. e., no net flux of ions ), the membrane potential must be equal to the Nernst potential.

When rain came, the swamp overflowed into the ditch, washing Tuna-roa into the meshes of the net.

When a mail server receives a connection from a client, and wishes to check that client against a DNSBL ( let's say, dnsbl. example. net ), it does more or less the following:

When net chloride flows out of the cell, GABA is excitatory or depolarizing ; when the net chloride flows into the cell, GABA is inhibitory or hyperpolarizing.

When the net flow of chloride is close to zero, the action of GABA is shunting.

When the temperatures are the same, no net evaporation of water in air occurs ; thus, there is no cooling effect.

When a positive voltage is applied to anode of the diode from the circuit, more holes are able to be transferred to the depleted region, and this causes the diode to become conductive, allowing current to flow through the circuit.

When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state ; in simple terms, it is the possibility of a risk-free profit at zero cost.

According to the theorem, it is possible to expand the power ( x + y )< sup > n </ sup > into a sum involving terms of the form ax < sup > b </ sup > y < sup > c </ sup >, where the exponents b and c are nonnegative integers with, and the coefficient a of each term is a specific positive integer depending on n and b. When an exponent is zero, the corresponding power is usually omitted from the term.

When the heat release oscillations are in phase with the pressure oscillations, the Rayleigh Index is positive and the magnitude of the thermo acoustic instability is maximised.

When the circuit is solved, the circuit element currents may have positive or negative values.

When pointing the thumb away from the origin along an axis, the curvature of the fingers indicates a positive rotation along that axis.

When A, B and C are sorted in a counterclockwise order, this determinant is positive if and only if D lies inside the circumcircle.

When the cell is being charged, the anode becomes the positive (+) and the cathode the negative (−) electrode.

When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.

When considering the band structure and binding energy of a metal, it is necessary to take into account the positive potential caused by the specific arrangement of the ion cores – which is periodic in crystals.

When and are either both positive or both negative, then can also be thought of as asserting that both and have the same remainder.

When the voltage of C1 right-hand plate ( Q2 base voltage ) becomes positive and reaches 0. 6 V, Q2 base-emitter junction begins diverting a part of R2 charging current.

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 the odds of drawing a card that wins the pot are numerically higher than the pot odds, the call has a positive expectation ; on average, you win a portion of the pot that is greater than the cost of the call.

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

When V is positive, electrons in the tip tunnel into empty states in the sample ; for a negative bias, electrons tunnel out of occupied states in the sample into the tip.

When the system is used for physical three-space, it is customary to use positive sign for azimuth angles that are measured in the counter-clockwise sense from the reference direction on the reference plane, as seen from the zenith side of the plane.

When measured as a function of mean solar time rather than uniform time, the effect appears as a positive acceleration.
