What is the mass of an object if it is attracted with a force of 0.2 N to another object of mass 7000 kg when the objects are 0.04 m apart?

Notice how they put future which of the clouds shown would indicate a possible future rain storm? a) b) c) d)

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?

The receptor cells that convert light energy into neural signals are called
