The planets have (their) moons. So the answer would be planets.
Answer:
All
Explanation:
I'm not sure what you meant but Newton's third law which basically states that every action has an equal and opposite reaction applies to <em>all</em> objects. So I think the answer is all.
Metamorphic rocks form when pre-existing or parent rocks (whether igneous, sedimentary, or even metamorphic) are altered by heat, pressure, and the chemical activity of fluids. When the dominant altering factor is heat, usually from direct contact , it may undergo fundamental change in texture and recrystallization is called contact metamorphism. While regional metamorphism, where rocks texture and minerals are changed by heat and pressure.
Waves transport energy along a medium without transporting matter. The amount of energy carried by a wave is related to the amplitude of the wave. Thus, the higher the wave is from the resting line, the more energy is put in and vice-versa.
Answer:
The magnitude of the torque about the origin is 108 N-m.
Explanation:
Given that,
Mass of the stone, m = 2 kg
Length of the string, l = 0.5 m
Angular velocity of the stone, 
The circle is parallel to the xy plane and is centered on the z axis, 0.75 m from the origin, r = 0.75 m
Firstly it is required to find the centripetal force acting on the stone. It is given by :
F = 144 N
Now the magnitude of the torque about the origin is given by :
So, the magnitude of the torque about the origin is 108 N-m. Hence, this is the required solution.
