Answer:
F = 1,875 N
Explanation:
force=
∆H = m∆V
where ∆H ----> change in momentum.
( final momentum - initial momentum )
and ∆V ----> change in velocity
( final velocity - initial velocity )
and m ----> is mass
then f =
= 1,875 N
I think it would be the scientific method.
When paper burns, some of the chemical compounds in the
paper combine with oxygen in the air and become different
chemical compounds. That's a chemical change.
When iron rusts, or copper or silver turns green, that's the result
of the metal at the surface combining with the oxygen in the air and
forming a new chemical compound. Those are chemical changes.
When water evaporates, H₂O in the liquid phase gains thermal
energy and changes to H₂O in the gaseous phase. No chemical
compounds are lost, gained, or changed to other compounds.
It's just a physical change.
I do not have a clue i need to answer so i can ask questions sorry
<span>A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface.
P and S waves are body waves. Each type of wave shakes the ground in different ways</span>
