Solve v= d/t for t when d=30 and v=200

In the image, the arrow is pointing to a celestial object. which attribute disqualifies the object from being a planet?

=force × distance a. work b. velocity c. pressure d. momentum

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
