The universe beyond any visible light source or heat source where temperature is below -315 degrees. Is this universe frozen like an "aro-gel" structure where all particles, atoms, molecles, quarks etc... are frozen in motion and seperated into its most singularity self and at the same time suspended at equal distance from every other singularity dot.

*note* that the high population density of Java PREDATES globalization and industrialization and colonization by the Dutch, etc.
Java has ALWAYS been densely populated. I want to know what the historical reason for this is.
Thanks.

Besides its weight, a 2.8 kg object is subjected to one other constant force. The object starts from rest and in 1.20s experiences a displacement of (4.20i - 3.30j) m, where the direction of j is the upward vertical direction. Determine the other force.

I don't understand exactly what their asking for....is it an exact number or the direction? How do would you solve this? Help, thanks.
