Answer 1

C1 = (1,2) R1 = √1+4–1 = 2

C2 = (6,8) R2 = √36 + 64 – 91 = 3

C1C2 = √61

R1+R2 = 5<√61

Circles are far apart

So no of tangents = 4

Answer 2

Step-by-step explanation:

Hey!

Given=mass of moon=7.36×10^22

mass of earth=6.37×10^24

radius of moon=1.74×10^6

g=GMm/Rm^2

g=6.67×10^-11*7.36×10^22/(1.74×10^6)^2

g=1.6ms-2

we can put the value of g=9.8ms-2

so,gm/ge=1.6/9.8=1/6

hope it helps you
