Suppose an asteroid has a tiny moon orbiting around it (which does occur). If the moon is 1.8 km wide, is 114 km from the center of the asteroid (which is 54 km long), and assuming the moon has a circular orbit around the asteroid of period 30 h), what is the mass density of the asteroid (if its volume is 1.39 x 104 km3)

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.

The answer is: c. from underground
