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.

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.

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.

What is the wavelength of an electron moving with a velocity of 2.5 x 108 cm s1?

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.
