Figure 2 shows two atoms represented as solid spheres. A hydrogen atom has a radius of 2.5 × 10^–11 m
Determine the radius of a magnesium atom.
Use measurements from Figure 2.

The gravitational attraction between two objects will if one object acquires more mass .

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
