Question

The acceleration due to gravity on the surface of moon is 1.62ms-2 The radius of moon is 1740km. Find the mass of moon.

​

Answer 1

Inland taipan

The inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD 50 value of 0.025 mg/kg SC.

Answer 2

Explanation:

Given:-

Radius of moon = 1740Km = 1740000m

acceleration due to gravity = 1.62m/s-2

g = acceleration due to gravity

G = gravitational constant(6.67 * 10^-11)

m = mass

r = radius

g = G*(m1m2/r^2)

m = (g * r^2)/G

m = (1.62 * (1740000)^2)/(6.67 * 10^-11)

m = 7.34767309 × 10^22 Kg
