When uncertainty in position of an electron is zero what will be uncertainty in momentum?

Werner Heisenberg's (1901-1976) uncertainty principle: ∆x∙ ∆(mv) ≥ h / 4π x = uncertainty; m = mass; v = velocity To solve for ∆x... ∆x = h / 4πm∆v

What is the angular momentum of an electron in 2s-orbital?
Zero.
If you are at rest do you have momentum?
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
Example for a body with zero momentum and some kinetic energy?
No solution. Zero momentum (MV) means either zero mass or zero velocity. Either one results in zero kinetic energy (1/2 MV2).
How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
What name is given to a region of an electron probability density graph where the probability of finding the electron is zero?
The region of zero electron density is called a "node."
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
What is the angular momentum of an electron in 2s-orbital?
Zero.
Under what circumstance can you know the velocity of an electron with great accuracy?
Only when the position is zero.
What is the state of a body having zero momentum?
Zero momentum means that the state of a body is also zero, and is static.
Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
Why do electron n positron move in opposite directions in pair production and how does momentum is conserved when they move in opposite directions?
They move in opposite directions when in a magnetic field because they have opposite charges. The force on a particle depends on its charge -- make the charge completely opposite, and the force on it will be completely opposite. Momentum is conserved when they move in opposite direction (that is, in their center of mass frame) because their respective masses are identical. One electron mass moving in one direction plus one electron mass moving in the opposite direction means a total momentum of zero. The system begins with zero momentum and ends that way.
If you are at rest do you have momentum?
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
What is the energy during momentum?
There is no "energy during momentum". A moving object has both non-zero momentum, and non-zero kinetic energy.
Does a body moving with uniform acceleration have momentum?
As long as it has a non-zero velocity, it will have a non-zero momentum.
What does conversation of momentum mean?
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
When ever an object is standing still the momentum is?
When an object is still it has no momentum. That is, the momentum is zero.
What is momentum of inertia?
Zero
