Given momentum is conserved and is mv
if
mass is the same and va=2vb
then momentum is m(2vb + vb)
if collision is elastic (bounces off)
then m(2vb + vb) = m(vfa + vfb)
3vb = vfa + vfb
meaning final velocities would be different
if collision is inelastic (sticks together)
then m(2vb + vb) = (m+m)vf
meaning final velocity would be same
is this what you wanted?
The best predictor of the radioactive nature of an isotope is the neutron-to-proton ratio of the atom. Isotopes are atoms of elements having the same number of protons however they don't have the same number of neutrons. Each isotope of an element will have different values of mass number.
Answer: Melting, evaporation and sublimation.
I don't know your statement, but one explanation for this is that Russia is mostly located on land, away from water and Florida is surrounded by water.
Water takes up the heat from the environment, so it has the effect of making the temperatures of objects around it milder: cooling down when hot, warming up when too cold.
