What are some tasks that organelles perform inside of a cell?

What part of the ear is names after tools, such as the hammer and the anvil?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (
