2 If the mass of a proton Y's 1:67X10-2759 and the mass of an election is altx 1034
Calculate the force of gravitation between
i a protron and an election
two electrons
in two protrons
Take G= 6.67X 10" N m² kg , distance
between the protrons = 4.0m, distance
between the electrons = 2x 102m,
distance between the electrons ex 10²m
distance between the proton and the
electron -
5.4 x 10-11 m

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
