Answer:
The kinetic energy of an electron is
Explanation:
Given that,
Distance = 0.1 nm
We need to calculate the momentum
Using uncertainty principle
Where, = change in momentum
= change in position
Put the value into the formula
We need to calculate the kinetic energy for an electron
Where, P = momentum
m = mass of electron
Put the value into the formula
Hence, The kinetic energy of an electron is
Hello
1) Since there is no friction between the ice and the track, there is no loss of energy in the motion, so we can apply the law of conservation of energy.
The total energy E (sum of potential energy P and kinetic energy K) must be conserved:
2) At the beginning of the motion, the total energy of the object is just potential energy:
where m is the mass,
is the gravitational acceleration, and 
is the initial height of the body.
3) At the end of the motion, this potential energy has converted into kinetic energy, and so the total energy at this point is
where m is the mass and v is the final velocity of the object.
4) We said that the total energy must be conserved, therefore we can write
and so:
from which we can find v, the velocity:
