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.

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.

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.

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.

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.

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.

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

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.

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.

No. Even a single electron has momentum.

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.

The de Broglie wavelength of an electron is given by the equation λ = h / p, where h is the Planck's constant (6.626 x 10^-34 J s) and p is the momentum of the electron (mass x velocity). The momentum of the electron can be calculated as p = m * v, with m being the mass of the electron (9.11 x 10^-31 kg) and v being the velocity (2.5 x 10^8 cm s^-1). Plugging in the values, we can find the wavelength of the electron.
