circular conducting loop of wire has a radius of 5.0 cm and a resistance of 60 :. Perpendicular to the plane of the loop is a uniform magnetic field of strength 7.5 T. This field is then reduced to zero over time. How long (in seconds) should it take the field to reduce to zero, if we want the induced current in the loop to be 0.005 A

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?

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

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?
