Calculate the force of gravity between two obejcts of masses 1300kg and 7800kg which are 0.23 apart

Given:                                                                                                        

m1= 13000 Kg     (mass of the 1st object)                                                                                 

m2= 7800 kg        (mass of thesecond object)                                                                            

 r= 0.23 m  (distance between the two objects)

Now F= (G×m1×m2)÷r^2

G= 6.67x10^-11 Nm^2/Kg^2 (G is the gravitational constant)

F = (6.67x10^-11 ×1300×7800) ÷ (0.23)^2 =  0.0127852N

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.​
