The nucleus of an atom can be modeled as several protons and neutrons closely packed together. each particle has a mass of 1.67 ✕ 10−27 kg and radius on the order of 10−15 m. (a) use this model and the data provided to estimate the density of the nucleus of an atom.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
