In beta decay of a nucleus, an electron is emitted. if the nucleus is assumed to consist of protons and electrons, calculate the minimum energy of the electron confined within a nucleus of radius 1.5 fm., using heisenberg's uncertainty relation. calculate also the minimum energy of the proton confined within the nucleus.

c

explanation:

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
