If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

Similar statements apply to the dual situation of terminal morphisms from U. If such morphisms exist for every X in C one obtains a functor V: C → D which is right-adjoint to U ( so U is left-adjoint to V ).

If further digital communication is desired, it may take place via external data modems or via optional modems built into the ALE terminal.

If the input buffer is empty ( because no characters have been typed since the last end-of-line or end-of-file ), a program reading from the terminal reads a count of zero bytes.

If the terminal driver is in raw mode it no longer interprets control characters, and the EOT character is sent unchanged to the program, which is free to interpret it any way it likes.

If we define control characters as non-graphic, or as having a special meaning for an output device ( e. g. printer or text terminal ) then any escape character for this device is a control one.

If the terminal moves to another access interface, that terminal assumes the identity of the new interface.

If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube.

If the particles are falling in the viscous fluid by their own weight, then a terminal velocity, also known as the settling velocity, is reached when this frictional force combined with the buoyant force exactly balance the gravitational force.

If a particle is travelling a velocity other than its terminal velocity it approaches the terminal velocity exponentially with an e-folding time equal to the relaxation time:

If an object is both initial and terminal, it is called a zero object or null object.

If loops are permitted, then the graph with a single vertex and one loop is terminal.

If the Esc key and other keys that send escape sequences are both supposed to be meaningful to an application, an ambiguity arises, if a terminal or terminal emulator is in use.

If clinical death is expected due to terminal illness or withdrawal of supportive care, often a Do Not Resuscitate ( DNR ) or " no code " order will be in place.

If it is another saccharide, the resulting units can be termed as being at the reducing end or the terminal end of the structure.

If a positive potential V < sub > G </ sub > is applied at the gate terminal with respect to the cathode, the breakdown of the junction J < sub > 2 </ sub > occurs at a lower value of V < sub > AK </ sub >.

If the particles are falling in the viscous fluid by their own weight due to gravity, then a terminal velocity, also known as the settling velocity, is reached when this frictional force combined with the buoyant force exactly balance the gravitational force.

If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube.

If a keyboard is connected, the main video display will be used as the console terminal and Open Firmware can be re-entered at any time by pressing Stop-A ( L1-A ) on the keyboard.

If the following is input into a terminal:

If we define r < sub > i </ sub > as the displacement of particle i from the center of mass, and v < sub > i </ sub > as the velocity of particle i with respect to the center of mass, then we have

If the vector field represents the flow velocity of a moving fluid, then the curl is the circulation density of the fluid.

If air is heated in a region it will expand in all directions such that the velocity field points outward from that region.

If called upon, the neighbouring amoeba midwife travels up to 200 μm towards the dividing amoeba, usually advancing in a straight trajectory with an average velocity of about 0. 5 μm / s.

If ω is directly proportional to k, then the group velocity is exactly equal to the phase velocity.

If the waves are propagating through an anisotropic ( i. e., not rotationally symmetric ) medium, for example a crystal, then the phase velocity vector and group velocity vector may point in different directions.

If the bullets have to travel a varying distance from the case to the point where they engage the rifling, then this can result in variations in pressure and velocity.

If a frictional force ( damping ) proportional to the velocity is also present, the harmonic oscillator is described as a damped oscillator.

If the initial and final positions are sufficiently close together, the maximum acceleration or maximum velocity may never be reached.

If there is a difference in velocity between two disks, any matter transferred between them must be accelerated by the disk accordingly.

If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force

If the center of mass is moving at velocity, the momentum is:

If one body has much greater mass than the other, its velocity will be little affected by a collision while the other body will experience a large change.

If the cannon fires its ball with a low initial velocity, the trajectory of the ball curves downward and hits the ground ( A ).

If the cannonball is fired with sufficient velocity, the ground curves away from the ball at least as much as the ball falls — so the ball never strikes the ground.

If, e. g., u is the speed of a particle, then the straightforward notation for its velocity is u, < u > u </ u >, or.

If the rotor disk is to be tilted forward ( to gain forward velocity ), its rotation requires that the downward net force on the blade be applied roughly 90 degrees ( depending on blade configuration ) before, or when the blade is to one side of the pilot and rotating forward.

If an object moves with angular velocity ω around a circle of radius r centered at the origin of the x-y plane, then its motion along each coordinate is simple harmonic motion with amplitude r and angular frequency ω.

If the world is reflected in a mirror which switches the left and right side of the car, the reflection of this angular velocity vector points to the right, but the actual angular velocity vector of the wheel still points to the left, corresponding to the minus sign.

If the group velocity ( see below ) is wavelength-independent, this equation can be simplified as:

If a photon rocket begins its journey in low earth orbit, then one year of thrusting may be required to achieve an earth escape velocity of 11. 2 km / s if the vehicle is already in orbit at a velocity of 9, 100 m / s, and 400 m / s additional velocity is obtained from the east to west rotation of the earth.
