Under standard conditions on earth, 1 kg = 9.8 newtons. what would the mass of an object be on mercury if the same object weighed 45.0 newtons on earth?

this could be newton#'s law of cooling. the cooling curve is exponential

3. dark matter

empty space could also be a simple vacuum

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
