How far apart are a 900kg car and an 80kg man if they experience a gravitational attraction of 1 n?

F = G M₁ M₂ / R²

G = 6.67 x 10⁻¹¹ m³ / kg - s²

Without units . . .

1 = (6.67 x 10⁻¹¹) (900) (80) / R²

R² = (6.67 x 10⁻¹¹ x 900 x 80)

R² = 4.8 x 10⁻⁶

R = √(4.8 x 10⁻⁶)

R = 0.0022 meter

R = 2.2 millimeters

The man's center of mass has to be 2.2 millimeters from the car's center of mass.  The car's center of mass may be somewhere in the back seat, but the man's center of mass is inside him, behind his belly-button.  So the whole thing is pretty much impossible.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
