Bonsoir

Fterre/lune = G × Mterre × Mlune / d²

Fterre/lune = 6,67.10⁻¹¹ × 5,97.10²⁴ × 7,35.10²² / (384 400 000)²

Fterre/lune = 1,98.10²⁰ N

I only preach of avarice and the like, And in this way induce them to be free In giving cash—especially to me. Because my only interest is in gain; I’ve none whatever in rebuking sin. No, none! When they are pushing up the daisies, Their souls, for all I care, can go to blazes. –The Canterbury Tales, Geoffrey Chaucer How is the Pardoner characterized in this passage?
