I believe that this question has the following choices to
choose from:
placer deposits
fossil compaction
hydrothermal solutions
igneous processes
Actually among all, I have never encountered an ore that
formed due to fossil compaction. I suppose we can get minerals such as marble
or lime but not ores. So the answer is:
<span>fossil compaction (answer)</span>
Answer:static, sliding, rolling,
Explanation:
Answer:
The force exerted by the rope on her arms is 273.7 N = 0.274 kN
Explanation:
Step 1: Data given
Mass of the ice skater = 55.6 kg
Velocity = 1.73 m/s
She then moves in a circle of radius 0.608 m around the pole.
Step 2:
Force exterted by the horizontal rope is the centripetal force acting on theice skater:
Fc = M*ac
⇒ with ac = v²/r
Fc = M * v²/r
Fc = 55.6 * 1.73²/0.608
Fc =273.69 N
The force exerted by the rope on her arms is 273.7 N = 0.274 kN
