No, the momentum of an electron can change depending on its velocity and direction of motion. Momentum is a vector quantity that is the product of an object's mass and velocity. So if the velocity of an electron changes, its momentum will also change.

What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
The characteristic wavelength of an electron accelerated through a potential field can be calculated using the de Broglie wavelength formula: λ = h / p, where h is the Planck constant and p is the momentum of the electron. Given the speed of the electron, momentum can be calculated as p = m*v, where m is the mass of the electron. Once the momentum is determined, the wavelength can be calculated.
Does an object moving at a constant speed have momentum?
Yes, an object moving at a constant speed does have momentum. Momentum is the product of an object's mass and velocity, so as long as the speed is constant, the momentum of the object will also remain constant.
Is the momentum of an object moving in a circular path constant?
No, the momentum of an object moving in a circular path is not constant. The direction of the velocity of the object changes constantly, leading to changes in its momentum.
Can an object in free fall has a constant momentum?
Yes, an object in free fall can have a constant momentum if no external forces are acting on it. In free fall, the only force acting on the object is gravity, which causes a constant acceleration. As long as no external forces are present, the momentum of the object will remain constant.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
a proton and electron have the same kinetic energywhich has longer wavelength?
the electron would have the longer wavelength b/c the proton has more momentum and λ=h/p (λ is wavelength, h is planc's constant and p is momentum)
What does planck's constant divided by 2times of pi indicates in Bohr's atomic theory?
In Bohr's atomic theory, Planck's constant divided by 2π represents the angular momentum of the electron in a stable orbit around the nucleus. This value is used to quantize the angular momentum of the electron in discrete levels, as proposed by Bohr in his model of the atom.
What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
The characteristic wavelength of an electron accelerated through a potential field can be calculated using the de Broglie wavelength formula: λ = h / p, where h is the Planck constant and p is the momentum of the electron. Given the speed of the electron, momentum can be calculated as p = m*v, where m is the mass of the electron. Once the momentum is determined, the wavelength can be calculated.

Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What is the statement that niels bohr made about the angular momentum of the electron in the hydrogen atom?
Niels Bohr's statement about the angular momentum of the electron in the hydrogen atom is that the angular momentum of the electron is quantized and can only take on certain specific values that are integer multiples of Planck's constant divided by (2\pi). This formed the basis of the Bohr model of the atom, which helped explain the stability of atoms and the discrete nature of their energy levels.
If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.
Does an object moving at a constant speed have momentum?
Yes, an object moving at a constant speed does have momentum. Momentum is the product of an object's mass and velocity, so as long as the speed is constant, the momentum of the object will also remain constant.
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
Suppose an electron is accelerated from rest through a potential difference of 150kV. What wavelength shoud it have?
The wavelength of the electron can be calculated using the de Broglie wavelength formula, which is λ = h/p, where λ is the wavelength, h is the Planck constant, and p is the momentum of the electron. The momentum of the electron can be calculated using the relation p = sqrt(2mE), where m is the mass of the electron and E is the energy gained by the electron from the potential difference. By substituting the given values into these equations, you can calculate the wavelength of the electron.
What does Ħ mean?
A modified form of Planck's constant called h-bar (ℏ), or the reduced Planck's constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum. For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h-bar.
Does an object have to be heavy in order to have momentum?
No. Even a single electron has momentum.
