Answer: have "cis C=C double bonds" and "liquid" at room temperature.
Explanation:
The unsaturated fatty acids have one or more C=C double bonds in the cis formation. Thus, this results in the molecules not been as stable as the saturated fats. They have weaker intermolecular bonds thus resulting in lower melting point . The consequently results in it being liquid at room temperature.
velocity of object just before hitting the ground = 10 m/s
10 m/sExplanation:
here's the solution : -
=》mechanical energy is always constant, when the object is at the top of the building , the object has potential energy but no kinetic energy,
so, at the top of the building the mechanical energy = potential energy = 100 J
but at when it is dropped from the building, the whole potential energy get converted into kinetic energy, just before reaching the bottom .
so, mechanical energy in the object just before hitting the ground = kinetic energy
( potential energy = 0 )
So, kinetic energy = 100 J
now, we know
=》
( since, mass = 2 kg )
=》
=》
=》
so, velocity of object just before hitting the ground = 10 m/s

Answer:Arctic circle
Explanation:
Arctic circle is one of the circles of latitude. It is located at the northern region if the equator and passes through more than one continent. These continent includes: North Asia,
Northern America, and
Europe.
In these continent, it passes through eight known counties. These countries includes: Canada, Russia, Norway, Sweden, Finland, Denmark, Alaska and Iceland. It covers 4% of the Earth surface and it's climatic conditions are extreme.
