I have not seen any significant differences in the walking sticks themselves, but I do find that the bramble in the ones at school dries out much faster. Of the three insects mentioned, the Indian stick is the only one I have witnessed near a water dish. We do spray our tanks daily, however, (except for weekends).
Problem 2 A 1000 kg car has four 10 kg wheels. When the car is moving, what fraction of its total kinetic energy is due to rotation of the wheels about their axles? Assume that the wheels have the same rotational inertia as uniform disks of the same mass and size.he platform has a mass of 150 kg, a radius of 2.0 m, and a rotational inertia of 3.00 kg Â· m 2 about the axis of rotation. A 60 kg student walks slowly from the rim of the platform toward the center.
The ultimate source of this energy is the Earthâs rotation, to which the Moon and the Sun provide a gentle brake, resulting the generation of frictional heat and the slowing down of the Earthâs rotation (days were two hours shorter 600 million years ago). Some researchers sa y that the vast majority of the heat in Earth's interiorâup to 90 percentâis fueled by the decaying of radioactive isotopes, while other scientists claim that heat from radioactive decay contributes about half of Earthâs total heat flux. 2  More here.
