Aparticle of mass m is confined inside of a spherical cavity of radius ro. the potential is spherically symmetric and can be written in the form: v(r)-0 for r < ro, and v(r)-oo for r = ro in other words, there is an infinite potential barrier at r 1. 2. ro. the particle is in the 0 state. solve the radial schrodinger equation and use the appropriate boundary conditions to find the ground state radial wave function r(r) and the ground state energy express your views on how you could find the pressure on the surface of the sphere exerted by the particle when it is in the a. b. 0 ground state.

A12-kg bag of groceries is tossed onto a table at 4.0 m/s and slides to a stop in 2.2 s . modify the equation fδt=δ (mv) to find the force of friction.

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you

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.
