Velocity of a fluid particle at centre of pipe is?
The velocity of a fluid particle at the center of a pipe in a fully developed flow is half of the maximum velocity in the pipe. This is known as the Hagen-Poiseuille flow profile for laminar flow.
A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?
The instantaneous acceleration of the particle is equal to 0 when the velocity of the particle is at a maximum or minimum. This occurs at the points on the graph where the slope of the velocity-time graph is horizontal or the velocity reaches a peak or trough.
What is particle velocity at the extreme end of vibration?
At the extreme end of vibration, the particle velocity is at its maximum value. This occurs when the particle reaches the peak amplitude and changes direction. It then slows down to a stop before moving in the opposite direction.
What information can be inferred from Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion?
From Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion, we can infer the amplitude, period, and phase of the motion. The amplitude is the maximum velocity reached by the particle, the period is the time taken to complete one full cycle of motion, and the phase indicates the starting point of the motion within the cycle.
What determine the maximum velocity of photoelectrons?
The maximum velocity of photoelectrons is determined by the energy of the incident photons in the photoelectric effect. The higher the energy of the photons, the higher the maximum velocity of the emitted photoelectrons.
Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
What is the maximum velocity and maximum acceleration of a particle in SHM in terms of amplitude and omega?
0 velocity

What is maximum at mean position for particle performing simple harmonic motion?
Velocity is maximum at mean position for particle performing simple harmonic motion. Another feature that is maximum at this position is kinetic energy.

How does one determine the maximum energy to which a deuteron can be accelerated in a cyclotron?
The final energy attained by a deuteron undergoing cyclotron acceleration depends on the design of the cyclotron. In some machines the final energy may be as low as 3MeV whilst in others, 25MeV. Above 25MeV reletavistic effects kick-in and the cyclotron needs to be more sophisticated in its design. It does depend on the cyclotron. Theres actually an equation for that. It takes into account the maximum radius of the orbit of the particles and the wavelength of the accelerating voltage. So for a given cyclotron with exactly specified values for radius and wavelength, the maximum kinetic energy of a particle depends on its rest energy and, hence, its rest mass. But heres an easy way to figure it out: If a given cyclotron can accelerate protons to an energy of say, 2 MeV, then deuterons can be accelerated to 4 MeV. Multiply by a factor of 2.
What is particle velocity at the extreme end of vibration?
At the extreme end of vibration, the particle velocity is at its maximum value. This occurs when the particle reaches the peak amplitude and changes direction. It then slows down to a stop before moving in the opposite direction.
Maximum displacement upward of a particle of the medium?
The maximum displacement upwards is given by the equation y=-vxv/2g. At the peak, the value of velocity is said to be v=0.

What determine the maximum velocity of photoelectrons?
The maximum velocity of photoelectrons is determined by the energy of the incident photons in the photoelectric effect. The higher the energy of the photons, the higher the maximum velocity of the emitted photoelectrons.
What is the condition for maximum velocity?
The condition for maximum velocity is acceleration equals zero; dv/dt = a= o.
Which spring has maximum velocity?
The spring has maximum velocity when it is at its equilibrium position or at maximum compression or extension. This is where the spring has stored the most potential energy, which is then converted into kinetic energy, resulting in the highest velocity.
