angle of 10.4 ◦ with respect to the vertical. Its center of gravity is 9.95 cm from its tip, its mass is 392 grams, and its moment of inertia is 11642.7 g cm2 . It is observed to precess 0.945 times per second. The acceleration of gravity is 9.8 m/s 2 . How fast is it spinning? Answer in units of rad/s

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
