Afree particle has kinetic energy equal to 35ev a)- what is the velocity of the particle? b)- if this velocity is known to within 0.2% accuracy, what is r of the position that particle? assume that the mass of the particle is 2 x 10^-26 kg. use h and give the answer in nm.

Given:

kinetic energy of free particle, KE = 35ev

1eV = J

mass of the particle, m = Kg

accuracy in velocity= 0.2%= 0.002

Solution:

a) We know that

KE =

v =

⇒ v =

v = m/s

b) From Heisenberg's uncertainity principle:

can you make it more obvious. i can't see it properly

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
