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.
Anything that moves has kinetic energy, written as KE (see also the pages on momentum). The amount of kinetic energy that an object has depends on how fast it is moving (its velocity) and it also depends on the mass of the object. Kinetic Energy = 0Â·5 x mass x velocity2. this is usually written as KE = Â½mv2.
