An early planetary model of the hydrogen atom consisted of a 1.67 x 10 -27 kg proton in the nucleus and a 9.11 x 10 -31 kg electron in orbit around it at a distance of 5.0 x 10 -11 m. In this model, what is the gravitational force between a proton and an electron?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

momentum of soft ball three times less than baskey ball

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

+15-35=-20

going in opposite directions
