The tools shown in the diagram are used for gardening. Each is made up of two levers that are attached to each other. The handles are the input arms and the cutting blades are the output arms.
Hand shears
Lopper
Which tool has a greater mechanical advantage and why?
The lopper, because its longer handles produce more output force with less input force.
The hand shears, because you can apply less force to the handles with one hand,
The lopper, because the input work is the same as the output work.
O The hand shears, because their shorter handles transfer force more quickly to the cutting blade.

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.
