Explanation:
Momentum of the system is a constant when there aren't external forces..
So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s
<h3><u>Answer;</u></h3>
Continental accretion
<h3><u>Explanation;</u></h3>
- The collision and joining of crustal fragments to a continent is called the continental<em><u> </u></em><em><u>accretion</u></em><em><u>.</u></em>
- <em><u>Accretion is the process through which materials such as sediment, volcanic arcs, or seamounts or blocks, etc. are added to the tectonic plate or land mass.</u></em> Many astronomical bodies, such as stars, galaxies or planets are formed by this process.
- Where the process of accretion has occurred the tectonic plates may have dense basaltic rocks which are indicative of oceanic lithosphere.
Water freezes at zero degrees Celsius (32 degrees Fahrenheit). The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. ... This is what happens when the ice cube (a solid) turns into water (a liquid)
Answer:
d=1.25 m
Explanation:
fd=.5mv2-.5mv1; 10(d)=.5(50)(.5)-0; 10(d)=12.5; d=12.5/10; d=1.25 m
80/60=
