Answer:
2
Explanation:
The rotational kinetic energy of the dumbbell is:
where I is the moments of inertia of the two point-like system
The translation kinetic energy is:
Therefore the ratio of the rotational kinetic energy to the translational (linear) kinetic energy is:
This question sounds like it came after some activity where
some forces were observed. Since we were not there, and
we don't know what the activity was, we don't know what forces
were observed, and we have no clue to how they might be related
to the motion of the Earth around the sun.
<span>Pollination is the process by which pollen is transferred to the female part of a plant. The stigma is the central part of the flower, that is supported by a style and is part of the female reproductive organ within plants. Its structure is optimised to promote pollination by having hairs, sticky surfaces and three-dimensional sculptures that capture and trap pollen.</span>
