The mass of Earth is 5.9742 x 10^24kg. The mass of the sun is 1.9891 x10^30kg

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

c. newton's third law of motion

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

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
